Marbles bouncing off a Speaker

I had a large bass speaker and I took it out of its case and connected it to a sound box and played a song on full bass and I could see the speaker bouncing up and down.

When this happened, I got some little marbles and watched them bounce off.

We also put some old batteries and some bigger marbles on the speaker, and we pretended that the batteries were fighting the marbles. Even though the batteries often hit each other off the speaker, it looked cool because the batteries did back flips and sometimes they did back flips right off the speaker. The marbles mostly won but once they drew when they both went flying out of the speaker at the same time.

It was amazing to see the force of the sound vibrations pushing and throwing the marbles around.
