Make chicken sounds with a cup

Make chicken sounds with a cup Long, long ago, instead of mice and monkeys, Reeko used chickens for all of his experiments (Reeko switched to lab rats and monkeys when one of his chicken experiments went terribly wrong). Chickens proved to be perfect for scientific exploration! They didn’t each much, they were easy to find, and when you were done with them, well, we all know that chicken soup is good for your health...

With it, we’ll make beautiful music… or noise,...

Skating on thin ice

Pressure - you feel it at school, your teacher feels it during class (yes, a room full of little scientists can be stressful for some teachers), and your dad feels pressure when Mom asks him for the tenth time to take out the trash. Here's an interesting experiment that demonstrates a different kind of pressure - the forces of scientific pressure and how it can affect other objects....

Plastic cups in love

What does a flying airplane and a pitcher's curve ball have in common. Well, besides the fact that both travel through the air at amazingly fast speeds - both are based on a principle called Bernoulli's principle. Bernoulli, (pronounced Burr New Lee) was a Swiss mathematician who liked to piddle around with these types of things. Now we get to piddle too......
