Just drag the sliders and see the collision that results! This simulation uses real physics, making the collisions realistic as well as cool! The 'Bounciness' slider is actually the coefficient of restitution times 100. 0 means completely inelastic particles, and 100 is perfectly elastic. Here are some common examples (approximate): Bean Bag - 0 Football - 55 Tennis ball - 65 Basketball - 75 Solid steel ball - 99
