I was watching David Letterman last night and he had on the young scientist. Heres the jist of the segment KID SCIENTISTS
1. Vicky Wei - 14 and in the 8th grade. Likes to swim and play tennis. Her favorite subject is science. Vicky has braces and she's had them for a few years. Dave can tell that they must be coming off soon and that her teeth will look terrific. Vicky's experiment involves a bucket of soapy water, a beachball, and a hydrogen peroxide mixture. Isn't that dangerous? Vicky says it isn't really unless there is a flame nearby. Dave reaches down and picks up a lighter from the demo table. He says, "Well, I'm glad there isn't a flame nearby."
After some trouble involving who gets what goggles and who gets the ear protectors, the experiment is about to begin. From the beach ball and a hose, bubbles are created in the small pool of hydrogen peroxide. Dave then scoops up the bubbles into his hands. Vicky then lights the bubbles with the lighter. When the flame hits the bubbles . . . BANG! A loud explosion! That was pretty cool and looks to be easy to do. What is the science that we learned here? Who cares? The ka-boom was cool

2. Zach Gold - 11 and in the 6th grade. Likes swimming and archery. Wants to be an industrial engineer when he grows up and build robots. Zach has a bearded dragon at home and a frog. And an older sister who sits on him.
What's Zach have for us tonight? He has a pool of non-Newtonian Fluid. It looks like pancake batter with a similar consistency when you pick it up. But when you run across the pool of non-Newtonian Fluid, you stay afloat like Jesus. Zach showed us, and then had Dave run across the pool, too. I forget the science we learned here.

3. John Ahn - 11 and in the 6th grade. Likes to drawer cartoons and play the saxophone and piano. He has two younger brothers and some fish at home. What does John have for us? He has four rolls of toilet paper attached to a leaf blower. When the leaf blower is turned on, the rolls of toilet paper quickly unroll making a wonderful visual. It has something to do with the Bernoulli Effect. I think I may have seen this before at "Stomp." It looked pretty cool.

And that was Kid Scientists, each from Kennedy Junior High School in Naperville, Illinois.

Now Zach did something I've never seen before or ever even heard of.
non-Newtonian Fluid. It is way cool
My daughter made some following these instructions.
get a cup fill it about 1/2 full of water and add cornstarch until it gets very pasty. then try to poke something into it. it will not go in, but if you just lay something on it it will sink!!
TRY ITWITH YOU KIDS.....

follow the google link to wikipedia and open the page on non-Newtonian Fluid and scroll down there is a video of some people walking across a swimming pool full of the stuff.
