after when it crystallizes (end of video), is it going to be hot?

Has anyone made a crystal meth joke yet?

I want to take this liquid, rig a system to suspend the seed so it can be raised and lowered, and then lower it into the liquid, pulling it slowly out. I expect some fun formations might occur!

I have a question. Why is it that during half of the crystallization process, there are some crystals forming around the edge of the dish, where the sodium thiosulfate isn't touching the seed crystal?

When you have a supersaturated solution it crystallizes on its own even if you just leave it in the dish. We added the seed crystal only to show how it works + its much faster and more obvious.

Shouldn't that tube be held by something other than bare hands, (albeit surgical gloves) Kids, use a clamp if you wish to attempt this. That said, it was enjoyable to watch :)

It took less than 50 sec to melt the whole quantity. If you are not familiar with holding a test tube for that long, not even a clamp would help :-)
