The object of the challenge is to balance all of the nails on the head of a single nail. All of the nails have to be balanced at the same time and cannot touch anything but the top of the nail that is stuck in the base. If you're really ambitious, you can try your luck at our large-scale version using landscape nails and a friend as the base. Enough of this idle chatter... get balancing!
The Tea Bag Rocket is really an adaptation of a classic science demonstration called the Ditto Paper Rocket. If you're old enough to have experienced Ditto paper, you'll recall the bluish-purple ink and that unforgettable smell of freshly printed copies. (Come to find out... both the Ditto machine solvent and the ink were highly toxic, but no one seemed to care back then.) Each piece of Ditto paper had a sheet of tissue paper that separated the two-part form, and it was this discarded piece of paper that kids used to make the "rocket." Since Ditto paper is a thing of the past, science teachers found a simple replacement - a tea bag.
It's an explosion of color! Some very unusual things happen
when you mix a little milk, food coloring, and a drop of liquid
soap. Use the experiment to amaze your friends and uncover the
scientific secrets of soap.
11-year-old scientist Greg Gassen had a great idea for his science fair project. The only problem? He didn't have access to liquid nitrogen. That's when he contacted our offices to see if Steve could help him locate some liquid nitrogen... and when Steve found out what Greg wanted to do, he decided to join in on the fun.
There's a lot of chemistry behind the simple lighting of a
candle. Oxygen is needed for the candle to burn, the melting
(vaporizing) wax provides the fuel and, of course, you need heat.
Remove any of the three (oxygen, heat or fuel) in the fire triangle
and the flame goes out. Yet another way to extinguish the fire is
to smother it with carbon dioxide gas. Because you have a flair for
doing cool science experiments, you'll learn how to blow out a
candle with a little style and showmanship.
