It will subliminate over a few hours, whatever you have leftover. Just don't put it in your freezer. It also doesn't seem to react well to being picked up with metal tongs(it squeals, LOL!) and I don't know what it would do to the sink. I would wrap it in a plastic bag just in case.
That stuff and liquid nitrogen are so fun to play with!
Haha, well I only have metal tongs, so this should be interesting. Thanks for the idea of the plastic bag, I'll do that!
