Aerogel-lo

This demonstration (on pages 9-11) uses gelatin and lead pellets to model how aerogel, a technology used by NASA spacecrafts, is used to capture comet particles. Instructions are provided on how to test the consistency of the gelatin "aerogel-lo", which must be prepared beforehand, and tips for running the demo. The procedure also includes background info about aerogel (first discovered in the 1930s), and limits of the "aerogel-lo" model, which is far more dense than real aerogel. Reflection questions are listed at the end.
