That does bring up another question, though, which is how hot the beads actually get in boiling water. The water itself boils at 212 degrees, but the pan is conducting heat from the burner and the beads are in direct contact with the bottom of the pan; glass is not a good heat conductor, but it is a conductor nonetheless, the beads therefore most likely get hotter than the water, even though the water is continuously cooling the surface of the pan and beads. Interesting.
Time to consult with my physicist friend again.
You could avoid this issue by going the opposite direction; from freezer to boiling water.
