Could you fill a ball with helium and make it bounce higher?

    My guess is that the material the ball is made of would have to be heavy enough to prevent it from floating. I don’t think  it would necesarily go higher, but take longer to come back down.

    It depends more on how fast the ball is going when it hits the earth and how much of that speed gets transferred to its upward velocity. It also depends on how big the ball is. In basic physics equations, we assume that air resistance is negligible for most calculations. Objects of different masses take the same amount of time to fall to the earth from equal heights due to how gravity interacts with them unless one object (such as a piece of paper or a feather) has a lot of surface area that is susceptible to wind resistance. Spheres are typically considered aerodynamic enough that air resistance does not affect them.
