I have a comment on this formula's instructions that should be added.
When testing the ooze, it is much faster to put a small amount in a boiled-egg holder, and let this much smaller volume cool off. By the time you've tested it, any mistakes will take only a few minutes to correct. The whole batch isn't solidified, and just needs to be reheated; which sould take about a minute as opposed to 20 when heating it from solid state.
also, I made the lamp, but when i turn on the lamp, the ooze immediately moves to the top when It can. What have I done wrong? I've only added a teaspoon of salt.
