Ice Cream Ball - Play & Freeze Maker

How to make ice cream in this clever contraption.

Just when you thought making ice cream was old hat, someone comes out with a cool contraption that makes you work for your dessert. With the Play & Freeze Ice Cream Maker, there's no need for electricity. Just add ice and rock salt in one end and ice cream mix in the other end--then have a ball as you shake it, pass it, or roll it. The ice cream mix can be as simple as cream, sugar, and vanilla, but the footwork on the ball is all you.

Materials

The Play & Freeze Ice Cream Maker comes in two sizes - standard and mega. You'll also need the ingredients to make ice cream. Here's the basic vanilla recipe...

Basic Vanilla Ice Cream

• 1 pint of Half & Half*
• 1 1/2 teaspoons vanilla
• 1/3 cup + 2 Tablespoons sugar
• Ice
• Rock salt

*Using whole cream makes a richer, creamier ice cream. Using part milk and Half and Half makes a lighter ice cream, but takes longer to freeze. Yield: about a pint of smooth and creamy ice cream.

Experiment

1. Fill the ice end with as much ice as possible and then add 1/2 cup of rock salt. (MEGA: Add 3/4 cup of rock salt).
2. The lid should be hand tightened - do not use the wrench! Mix up your ice cream ingredients in a container, then pour the mix into the end with the metal cylinder, leaving about an inch for expansion at the top.
3. Hand tighten the lid. Have a ball! Shake, roll, and pass it around as you mix and freeze the ingredients. It's not necessary to shake the ball...just motion will do it! After about 10 minutes (15 for the MEGA ball) open the ice cream end using the included plastic wrench.
4. Scrape the sides of the cylinder to mix up the ice cream using a plastic or wooden spoon (don’t use a metal spoon as it will scratch the cylinder). Then check the ice end.
5. Pour out the excess water and add more ice and up to 1/3 cup more rock salt to enhance the freezing ability. Close the lids securely and continue having a ball for approximately 5–10 more minutes. (15 for MEGA)

You now have about a pint (or quart for the MEGA ball) of delicious soft-serve ice cream. The consistency will vary based on the ice, your mix, the outside temperature, shaking frequency, etc. Once the ice cream is to the consistency of your liking, gently scoop it out, and enjoy!

How does it work?

What does the salt do? Just like we use salt on icy roads in the winter, salt mixed with ice in this case also causes the ice to melt. When salt comes into contact with ice, the freezing point of the ice is lowered. The lowering of the freezing point depends on the amount of salt added. The more salt added, the lower the temperature will be before the salt-water solution freezes. For example, water will normally freeze at 32 degrees F. A 10% salt solution freezes at 20 degrees F, and a 20% solution freezes at 2 degrees F. When salt is added to the ice, some of the ice melts because the freezing point is lowered.

Always remember that heat must be absorbed by the ice for it to melt. The heat that causes the melting comes from the surroundings (the warmer cream mixture). By lowering the temperature at which ice is frozen, you were able to create an environment in which the cream mixture could freeze at a temperature below 32 degrees F into ice cream.

Color Mixing Wheel - Sick Science

Create a wheel that will show you color and color mixing in a new way

Our visual division here at Steve Spangler Labs loves the science of color mixing. We've mixed gels, fizzing tablets, and even different colored lenses together to get the secondary colors. We needed something new. So, we found an amazing way to combine scientific principles of physics with the visual science of color mixing. Our discovery isn't just visually spectacular, it's scientifically sound!

Materials

• White corrugated cardboard
• Pointed tip scissors
• Red, blue, & yellow markers
• String or yarn
• Safety glasses

Creating the Color Mixing Wheel

1. Trace a circle onto a piece of white corrugated cardboard. Try to get the circle to be between 4 to 6 inches in diameter. Use something like a cream cheese lid, sour cream lid, or pickle jar.
2. Cut the traced circle out using the scissors.
3. Trace 3 smaller circles on the cardboard disc. Try to make each of the circles equal in width. This will enhance the visual aspect of the experiment.
4. Draw a single line through the middle of the disc that spans the entire diameter of the disc. Each of the three circles in the disc should now be divided in half.
5. Color half of the smallest circle blue and the other half yellow. Color the middle circle half red and half yellow. Finally, color the largest circle half blue and half red.
6. Grab an adult for this step: Using the pointed tip of the scissors, place two holes in the cardboard disc. Make sure the holes are an equal distance from the center of the disc and are about 1 inch apart.
7. Use the scissors to cut a piece of string or yarn that is 4 feet long.
8. Thread the string or yarn through each of the holes in the disc and tie the ends of the string together. Make sure the knot you tie is reliable and able to withstand a substantial amount of force. You are going to be tugging pretty hard on it.

Performing the Experiment

1. Start by holding the string on both sides of the disc with your hands. Make sure the disc is as close to the center of the string as possible.
2. Spin the disc in a motion similar to a jump rope. This is a quick way to get the string wound up.
3. Once the string on both sides of the disc is twisted, pull the string tight to get the Color Mixing Wheel spinning. It might take a little practice to get it just right.
4. Once you have the hang of how the Color Mixing Wheel works, you'll be able to keep it going as long as you want.

Observations

You may have noticed that the colors you put on the Color Mixing Wheel were the three primary colors: red, blue, and yellow. Once you started spinning the wheel, what did you notice about each of the three color circles on the cardboard disc?  What do you think makes this happen?

How does it work?

Let's start with the visual part of the experiment - color mixing.  The colors you put on the Color Mixing Wheel are the three primary colors: red, blue, and yellow.  When you combine two primary colors you get the secondary colors: green, purple, and orange. Obviously, the individual colors on the wheel are not mixing. The color mixing that happens is due to the speed at which the wheel is spinning as the string twists it.  The colors are spinning at such a rate that your brain is unable to process them as the individual colors that are on the wheel.  Instead, your brain takes a shortcut and creates the secondary colors.
Now, why does the string continue to twist?  The answer lies in physics and, in particular, momentum.  Once you have the string twisted, pulling on each end causes it to go tight.  When the string is pulled tight, it wants to be completely straight.  In going straight, the string unwinds from itself and causes the disc to spin one direction.  But the string doesn't stop once it's unwound. It speeds past and gets twisted again.  The momentum from pulling the string tight keeps the disc spinning until all the momentum is gone. Then you pull the strings tight again and set the disc spinning in another direction.

Eye Dropper Cartesian Diver

Is it mind control or just a clever science trick

Is it mind control or just a clever science trick? It's a classic science experiment using an eye-dropper, a soda bottle filled with water, and some great showmanship. Explore the science of Cartesian divers while amazing your friends with your telekinetic powers. Yeah, right!

This experiment is named after Ren Descartes (1596-1650), a French scientist and mathematician who used the diver to demonstrate gas laws and buoyancy.

Materials

• A plastic soda bottle with a cap
• A glass eye-dropper
• Water

Experiment:

1. Fill the plastic soda bottle to the VERY top with water.
2. Fill the glass eyedropper 1/4 full with water.
3. Place the eyedropper into the soda bottle. The eyedropper should float and the water in the bottle should be overflowing. Seal the bottle with the cap.
4. Squeeze the sides of the bottle and notice how the eyedropper (called a diver) sinks. Release your squeeze and it floats back up to the top. Squeeze again and observe the water level in the eyedropper (it goes up). Practice making the diver go up and down without making it look like you're squeezing the bottle. Amaze your friends with your ability to make the eyedropper obey your commands!

How does it work?

Squeezing the bottle causes the diver to sink because the increased pressure forces water up into the diver, compressing the air at the top of the eyedropper. This increases the mass of the diver causing it to sink. Releasing the squeeze decreases the pressure on the air at the top of the eyedropper, and the water is forced back out of the diver.

Candiru, The Amazon's Most Feared Fish

Maximum Length: Up to 6 inches
The Amazon's Most Feared Fish: The Candiru is a terrifying fish, even when stacked up against its fellow river monsters of the Amazon. But this parasitic freshwater catfish does not instill fear by way of its monstrous size. On the contrary, it's small, eel-like and so translucent that it can be nearly impossible to spot in the water, which makes it even more terrifying. Some claim this fish is the most feared in the entire Amazon region, and the fear stems from the fact that it has a knack for finding open orifices and working its way inside. Once inside another organism, the Candiru feeds on its host's blood, becoming increasingly swollen. The Candiru is the star of an urban legend — which turns out to be true — of a man who was urinating in the Amazon River when a 6-inch Candiru swam up his urine stream into his penis. The fish remained there for days, until a surgeon was able to remove it. The Most Horrific Candiru: Perhaps the most horrifying Candiru species of all is the Candiru asu. This small catfish is a voracious parasite. It uses its circular mouth and sharp teeth to bite flesh and then enter organisms, leaving behind a wound that looks uncannily like a bullet hole. The Candiru asu proceeds to feed on the organs, literally eating its victim from inside. Human corpses have been discovered in the Amazon filled with more than 100 of these river monsters. Scientists and coroners have determined that the victims may have even been alive and simply incapacitated when the Candiru asu struck. In Jeremy Wade's Words: "The candiru usually targets a big fish as its host, drinking blood from its gills, but occasionally they make mistakes. This has resulted in one of the most infamous legends to emerge from the Amazon: a man urinating in the river who has a fish swim up his penis."

Clingstone Mansion

This house is truly amazing. Not only because of his age who has been 103 years but also because it was founded in the middle of the sea. It is said that this house has stood since 1905, precisely on the rocks of Rhode Island in the middle of the sea. The house was often called Clingstone.

The house is quite large and quite comfortable. The house was built by JS Lovering Wharton, at a cost of 36,000 dollars, a distant cousin Henry Wood (79), which is now the owner.


Henry Wood with his ex-wife bought it in 1961 for $ 3600 U.S. dollars. Later he became the mansion renovation and is now an attractive and comfortable and has been inhabited for two decades more.
It was Wood's remarkable discovery.

Imagine the house has 23 rooms, and Wood still maintaining room architecture and its settings like 100 years ago. Every year, on certain holidays, Wood and his family invite dozens of friends to holiday in their place.

The house is indeed very large, therefore requiring a lot of people to be able to clean it. Understand it, Wood and his family did not live there every day. They only use it for vacation Manson. So when they come, the first thing to do is, work hard to make it shiny again.

But the volunteers, friends Wood, of course volunteered to help clean it up. They think it's interesting activity holidays filler. Wood and family and friends only came there when the summer. Usually they spend their week-long holiday period. While in winter, large Manson was silent and deserted. Boat them stay safe in the store on a floating dock near James Town Boatyard.

Packing for holiday Tips

Proper Packing Tips and Easy - mid-year holidays arrive soon. Before you go on vacation sure you're busy preparing it, for example, book a ticket transportation, planning accommodation and places to be visited. But before going there one that you definitely have to do: packing.

For some people, packing is a boring and most reluctant to do. While packing a pleasant thing, Lucky Magazine in May 2011 issue, deliver instructions and tips on how to correct and easy packing. Just 30 minutes, the following ways :

1. Avoid packing the less full as well as packing excessive, this can cause a lot of clothes wrinkle if there is space in your suitcase.

2. Use your warm clothes during the flight, so it will not take a lot of places in the suitcase. You'll need it when the aircraft cabin to grow cold.

3. Place the shoe along with items such as jewelry, socks and toiletries.

4. Roll clothes, do the folding. This will make the clothes less wrinkled and will make a lot of room for other items.

5. Use a small bag that can be used as a travel bag.

6. Use plastic bags to secure items that could cause problems and are easy to leak.

7. Separate items that light, bright and dark to avoid the dilution of color. Be careful with shoes made of velvet.

8. Choose clothing that shades of neutral and one that deserves to party.

9. Put toiletries in one mini place, so you should not need much space for this equipment.

10. At the back, wrap a small gift with a tie or socks to keep them safe and stable.

Frogs Who Has Long Vanished

A number of amphibian species status of the mysterious. They have not declared extinct, but also did not reveal its existence for decades. Some biologists carry out scientific expeditions to search for amphibian species are "lost" it, for example in the Congo. 

Having traveled for two years since 2009, scientists discovered five types of frogs which are all unique. The existence of the frogs that actually have been described since 1950, but they seemed to hide themselves from humans. 


Hyperolius leucotaenius 
One type of frog found in the Hyperolius leucotaenius. This frog has a transparent skin so that internal organs and even eggs could be seen. This frog species found in Elila River, southeastern Congo. 

Hyperolius leucotaenius has a green head and body-colored transparent plastic tub. This frog also has a pattern of yellow lines and tip-toe orange. Not yet clear reason why this frog has a transparent body. 

In addition, there are three species found in highland areas Itombwe, southeastern Congo. Two of them are Chrysobatrachus cupreonitens who have a body color of green and brown and Phrynobatrachus asper which have thick fleshy foot. 


Chrysobatrachus cupreonitens 


Phrynobatrachus asper 
Asper Phrynobatrachus species discovery is unique. This species was rediscovered in 2009 when a villager in the highlands of Itombwe offer dinner made from the frog to the scientists. 


Arthroleptis pyrrhoscelis 
One species from the highlands again Itombwe is fingered frog nail or Arthroleptis pyrrhoscelis. The development of the frog is unique because not pass tadpole phase. While the latter is Hyperolius chrysogaster species, found in the Kahuzi-Biega National Park, eastern Congo. 


Hyperolius chrysogaster 
Expedition rediscovery of the lost amphibians is led by El Greenbaum, biologist at the University of Texas at El Paso. The expedition was funded partially by the research committee and exploration, National Geographic Society. 

"The discovery of my team to prove that the forests were (in Congo) is still unexplored. There are a lot of biodiversity in there and not too late to redouble our efforts in conservation," said Greenbaum.

Wild Animal Facts

Each species of grasshopper has its own song. This is important, as the varied species cannot breed with each other. The female needs to be aware that she is listening to a male from her own species.

Compass termites of Northern Australia build tall nests that are wedge-shaped. They measure up to 3.5 m in length.

Flying frogs change color in the day. They are greenish-blue in sunlight and green in the evening. At night there are black.

Boas, as well as many other snakes have special heat-sensitive organs that are called pits. These pits are on their heads. They can detect the heat given by a warm-blooded animal standing close to them.

The king Cobra can grow to the length of 5.5 m, and is regarded as the largest poisonous snake in the world. A tiny amount of its poison can kill up to 30 people.

 

Anteaters protect their long claws by walking on their knuckles. This makes them look as if they are limping.

Bats eat all types of food. There is no restriction where their diet is concerned.



The hippopotamus’s eyes, ears and nostrils are on the top of its head. This enables it to stand or sit, almost completely covered by water with as little as possible showing above the surface.

The hippopotamus’s skin is protected by its own pink oily secretion known as ‘Pink sweat’.
