This is a simple lesson that shows how particles are
attracted to each other. Just have them drop paper into
still water (don't blow or move the water around) and
watch the bits of paper move toward one another.
We used bits of paper from my comb binder, but any
small pieces should work. I've heard that you could also
substitute talcum powder or baby powder, but we did not
try this.
