Albert Einstein's Logic Puzzle

So you want a hard brain teaser! Well, here it is.
It's purported that Einstein said 98% of the world's population could not figure out this logic problem. Try your hand at it.

There are 5 houses each with a different color. Their owners, each with a unique heritage, drinks a certain type of beverage, smokes a certain brand of cigarette, and keeps a certain variety of pet. None of the owners have the same variety of pet, smoke the same brand of cigarette or drink the same beverage.


  • The Brit lives in the red house.
  • The Swede keeps dogs as pets.
  • The Dane drinks tea.
  • Looking from in front, the green house is just to the left of the white house.
  • The green house's owner drinks coffee.
  • The person who smokes Pall Malls raises birds.
  • The owner of the yellow house smokes Dunhill.
  • The man living in the center house drinks milk.
  • The Norwegian lives in the leftmost house.
  • The man who smokes Blends lives next to the one who keeps cats.
  • The man who keeps a horse lives next to the man who smokes Dunhill.
  • The owner who smokes Bluemasters also drinks beer.
  • The German smokes Prince.
  • The Norwegian lives next to the blue house.
  • The man who smokes Blends has a neighbor who drinks water.
If you know the answer, just sent me an e-mail... or you can share with other guest how long you can solve this case... or... maybe you share some additionals clue for your friends... of course dont share your answer...

Ghost Lab

Im sorry... I'm not available for a long time.. Cuz im still a student so, i have to finish my examination first... Im really really sorry...

Ghost... what do you think about that word?? something bad?? something that sometimes following you?? They can see us, but we can't see them... Now, what happened if we try to make or find or something else to the unseeing creature??

Maybe one of you have already known about this TV programme... but i just share what i think interested...

Ghost Lab is a weekly American paranormal documentary television series that premiered on October 6, 2009 on the Discovery Channel. Produced by Paper Route Productions and Go Go Luckey Entertainment, the program is narrated by Mike Rowe. It follows ghost-hunting brothers Brad and Barry Klinge, who founded Everyday Paranormal (EP) in October 2007.
Everyday Paranormal is a paranormal investigation team whose stated mission is to "visit the most haunted places in America, find evidence, and test new theories to probe the existence of the afterlife" using a fringe-scientific approach.
In addition to Brad and Barry, the team included members Steve Harris, Hector Cisneros, and Katie Burr. Other members included Jason Worden, Ashlee Lehman (Formerly Ashlee Hillhouse), and Steve Hock. Ghost Lab remains the name of EP's mobile command center.
On October 14, 2009, Brad and Barry Klinge were interviewed on The Pat & Brian Show about the origins of Everyday Paranormal, current investigations, and equipment use. On October 30, 2009, Larry King interviewed the brothers via satellite on CNN's Larry King Live.

Release Date: 1 April 2011
Starring: Jake Gyllenhaal, Michelle Monaghan and Vera Farmiga


A man (Jake Gyllenhaal) wakes up on a train sitting across from a woman named Christina Warren (Michelle Monaghan). The woman seems to know him by the name Sean Fentress, but he doesn't seem to know her and appears uncertain of his own identity. After eight minutes, a bomb goes off on the train, and the man awakens to find himself strapped inside a small geodesic dome. There, Air Force Capt. Colleen Goodwin (Vera Farmiga) explains to him through a computer screen that he is actually Colter Stevens, a decorated army helicopter pilot, now on a mission to locate the maker of a bomb which destroyed a train headed into Chicago. This is to be accomplished using the Source Code, a time loop program that allows him to take over someone's body in a reenactment of their last eight minutes of life.

Stevens has no memory of how he became involved in the Source Code project; his last memory is of flying in a recent mission in Afghanistan while taking on enemy gunfire. Stevens' mission in the Source Code is to assume the identity of Fentress, one of the train's passengers, locate the bomb, discover who detonated it, and report back to Goodwin to prevent the bomber from detonating a larger dirty nuclear device in downtown Chicago, which could cause the deaths of millions of people. Goodwin and the Source Code's creator, Dr. Rutledge (Jeffrey Wright), tell him that the Source Code is not a simulation, but a visit into the past in the form of an alternate reality. He's told that he cannot truly alter the past to save any of the passengers, but that he must gather intel that can be used to alter the future and prevent a future attack. Goodwin assures Stevens that "everything will be OK."

The End of Space Shuttle Program

The end of the space shuttle program does not mean the end of NASA, or even of NASA sending humans into space. NASA has a robust program of exploration, technology development and scientific research that will last for years to come. Here is what's next for NASA:

NASA is designing and building the capabilities to send humans to explore the solar system, working toward a goal of landing humans on Mars. We will build the Multi-Purpose Crew Vehicle, based on the design for the Orion capsule, with a capacity to take four astronauts on 21-day missions.

We will soon announce the design for the heavy-lift Space Launch System that will carry us out of low Earth orbit. We are developing the technologies we will need for human exploration of the solar system, including solar electric propulsion, refueling depots in orbit, radiation protection and high-reliability life support systems.

International Space Station
The International Space Station is the centerpiece of our human spaceflight activities in low Earth orbit. The ISS is fully staffed with a crew of six, and American astronauts will continue to live and work there in space 24 hours a day, 365 days a year. Part of the U.S. portion of the station has been designated as a national laboratory, and NASA is committed to using this unique resource for scientific research.

The ISS is a test bed for exploration technologies such as autonomous refueling of spacecraft, advanced life support systems and human/robotic interfaces. Commercial companies are well on their way to providing cargo and crew flights to the ISS, allowing NASA to focus its attention on the next steps into our solar system.

NASA is researching ways to design and build aircraft that are safer, more fuel-efficient, quieter, and environmentally responsible. We are also working to create traffic management systems that are safer, more efficient and more flexible. We are developing technologies that improve routing during flights and enable aircraft to climb to and descend from their cruising altitude without interruption.

We believe it is possible to build an aircraft that uses less fuel, gives off fewer emissions, and is quieter, and we are working on the technologies to create that aircraft. NASA is also part of the government team that is working to develop the Next Generation Air Transportation System, or NextGen, to be in place by the year 2025. We will continue to validate new, complex aircraft and air traffic control systems to ensure that they meet extremely high safety levels.

NASA is conducting an unprecedented array of missions that will seek new knowledge and understanding of Earth, the solar system and the universe. On July 16, the Dawn spacecraft begins a year-long visit to the large asteroid Vesta to help us understand the earliest chapter of our solar system's history. In August, the Juno spacecraft will launch to investigate Jupiter's origins, structure, and atmosphere. The September launch of the National Polar-orbiting Operational Environmental Satellite System Preparatory Project is a critical first step in building a next-generation Earth-monitoring satellite system.

NASA returns to the moon to study the moon's gravity field and determine the structure of the lunar interior with the October launch of GRAIL. In November, we launch the Mars Science Laboratory named Curiosity on its journey to Mars to look for evidence of microbial life on the red planet. And in February 2012, we will launch the Nuclear Spectroscopic Telescope Array to search for black holes, map supernova explosions, and study the most extreme active galaxies.



Ice Cream Ball - Play & Freeze Maker

How to make ice cream in this clever contraption.

Ice Cream Ball - Play & Freeze Maker
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.


    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.


    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

    Color Mixing Wheel - Sick Science
    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!


    • 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.


    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.
