Re: [Phys-l] one of my students emailed this to me this morning. anyone have any good answers?



I would highly, highly recommend anyone (we educators and scientists, our students, and anyone interested about the natural world) read C.V. Boys' "Soap Bubbles and the Forces Which Mould Them". It's short, and fascinating, and I would have _loved_ to have seen his original talks. It's available on Project Gutenberg: http://www.gutenberg.org/ebooks/33370

Subject: [Phys-l] one of my students emailed this to me this morning. anyone have any good answers?

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
