WHAT’S
HAPPENING?
When you stretch the rubber band,
you can feel it heat up a little bit.
Your lips are very sensitive to heat,
so they can feel this small increase
in heat. Heat is generated because
the rubber band contains long
molecules called polymers, which
are all tangled up in a web like
spaghetti — just like gum! When
you stretch the rubber band, the
molecules slide past each other and
they generate heat as they do this.
Chewing gum is a form of natural
or synthetic rubber.

rubber band works best)

top edge of your lips, and then
stretch the rubber band. Repeat a
few times.
