I think beta decay is probably a bit more random. After all, there is
that whole uncertainty thing .. :)

Hard to say. It's certainly less amusing to watch, and certainly harder to
explain to a layman. :-)

What do you think drives the randomness of lava lamps? Pixies?

Oh, hell, just take a shot of the back of the lens cap every so often
(at high ISO), You'll get plenty of quantum randomness there. Or,
amplify an idle input from the sound card to a great extent. More
randomness, there, or a radio tuner tuned to a non-station, and use the
universe as your source of randomness. Plenty of sources. :)

Granted, individual atom decay is less likely to exhibit statistical
groupings. And you rarely have your radioactive source get too cold to be
random. :-)

electron motion converted to heat by squeezing them through a thin
filament of tungsten? Molecules of water and wax interacting with each
other once the wax is liquid.

Right, and occasionally my lava lamp acts completely non-random. It
forms a single blob that just hangs there.

I saw a laval lamp in a shop that had been left on for, like, the entire
day or something.
Do you know what a homogenous wax/water emulsion looks like? I do.

Someone shook it, I bet.

Well, the instruction on mine do say not to run it for too long. And,
just once, I accidentally left it on too long and it did emulsify to
some degree.

Mine always eventually became one single amorphous blob that would just
sit there.. But, didn't emulsify. I did shake it once just for fun. That
emulsified it. Took days for the wax to settle out of the water.

Interesting. After mine emulsified, I just turned it off, and fairly
quickly (about 20 minutes) all the wax sank to the bottom and co...
uh... no, sorry, I can't spell that word. :-S
