This was the second annual water rocket event at Imagination Station. We had all the supplies on hand for any visitor to build a water rocket and then head outside to launch it. We only had a few land in the river and none hit a building like happened in this segment. Overall it was a lot of fun.
With just a bit of standard air pressure, NOT compressed air, you can accelerate a ping pong ball to amazing speeds. Read more
Is there a better way to celebrate Mother’s Day than to freeze some flowers in liquid nitrogen? Probably, but flash freezing flowers and then watching them break like glass is pretty cool.

A new exhibit at Imagination Station, the earthquake platform. As part of engineering week I challenge local meteorologist Jay Berschback to build a stable tower on the Earthquake platform exhibit. Using only foam noodles and some cross-bracing he must construct a stable tower at least 5 stories tall. Find out if he can meet the challenge. Read more
Breaking glass is easy unless it’s tempered glass that can take quite a beating before breaking. Read more
Liquid nitrogen expands in volume about 8oo times as it changes from a liquid to a gas. What would happen if you tried to contain all that gas inside a 2 liter bottle? Find out.
Oobleck is a suspension of cornstarch and water that can behave like a solid or a liquid depending on how much pressure you apply. Try to grab some in your hand and it will form a solid ball in your palm just until you release the pressure, then it will flow out between your fingers. Materials that behave this way are classified as non-Newtonian liquids because their flow properties are not described by a constant viscosity. The name Oobleck comes from the 1949 children’s book, Bartholomew and the Oobleck, by Dr. Seuss. In the story a sticky liquid falls from the sky as a result of the king becoming bored with normal weather.
[dropcap1]W[/dropcap1]ith just a few gumdrops and some toothpicks you can build some pretty cool structures that are amazingly strong yet simple in design.
Hoop gliders are pretty cool cause they look like they shouldn’t really be able to fly as well as they do. Two hoops of paper taped to a soda straw actually fly pretty well. This is a pretty simple activity that you have to try just to see how well it really works! Read more
