Thanks for your information on the ferrimagnetic garnet. Once again
these videos are impressive, particularly the one of the water balloon.
Can somebody explain how is momentum conserved when the ball hits the
balloon? (it seems that there is a lot of water moving backward after
the ping pong ball hits the balloon!)
