Hello,

We here at the Kentucky Science Center are developing a science demonstration on the physics of falling and bouncing. The approx. 20-min show is conducted on our 3rd floor balcony and features dropping a variety of objects through our 40-ft atrium. For one of the elements we're attempting to show the transfer of energy and the Law of Conservation of Momentum by launching a small ball on top of a basketball. In our many trials we've only been able to perfectly align the balls once and have a small ball zoom past us to hit the ceiling of the building. Usually the balls will slide apart during the fall and either fail to make contact or launch at unpredictable angles.

Any suggestions out there for making our own astroblasters? The set of four balls on the plastic stick commonly seen in science supply catalogs is too small for our demonstration. This doesn't even need to be a row of four balls-two that can stay aligned and illustrate these principles would be great.

Thanks,

Andrew
