Collisions and Trajectories
Stomp, Swing! Rolllllllll. Crash? Using pendulums, catapults, marbles, and stomp rockets, the ScienceWiz Collisions & Trajectories set lets the kids (or adults, let's be honest) in your life set things in motion and learn about how objects start to move, how they keep moving, how they stop moving, and what happens they come in contact.
Collisions and Trajectories recommended for ages 8+.
