What did we do?

We searched NASA's Web site and found a way to test what microgravity is like. We made a "drop box" from a regular plastic storage container. We dropped it over a ledge and into an inflatable swimming pool. The height of the ledge was about 5 meters, enough to give us about 1 second of microgravity. We put a fizzing seltzer tablet in the drop box to see what happens to bubbles in microgravity. Second, we put a walking wind-up toy in the box, to see what it does. Last, we wondered what it would be like to ride on a swing in space. We put a small swinging pendulum in the box. We had a wireless video camera inside the box so we could see what happened during the drop. more...
