Hey all,
One of my HS students emailed this question to me this morning. We are
studying collisions in class now so I guess this is what sparked his
curiosity. Does anyone have a somewhat simple explanation I can give him?
"i was hoping you could help me out with something that i was curious
about. i was blowing bubbles in my cousins face while she slept and i
began to watch the bubbles. i noticed that they do one of four things
when they collide. they bump and move away, they bump and pop, they
fuse together into one super bubble or they half-fuse into this weird
siamese bubble. what is it that allows them to behave this way?"
Thanks,
Michael Barr
