This little lab setup was originally used as part of a learning activity (for something that, sadly, was not nearly as fun as chemistry!). One day, I'd like to expand on this old piece to create something more elaborate and fun (with even more explosions!).

Directions: Use the medicine dropper to place "catalyst fluid" into the top of various test tubes and beakers. The dropper behaves much like a real one - place it over the petri dish, click and hold, drag your fluid over to its destination, and then release.
