Hi All, I need some help with some very low tech stage pyrotechnics. I need to have a smallish cauldron on stage that is burning, and then which flares up when an actress throws something into it. The flare up also needs to last for a fixed amount of time. Any suggestions? I am particularly looking for some old school ideas as the theatre is really just a hall (in an Indian temple In Singapore - long story) and thus I have limited technology available. As an aside my day job is a science teacher so I have access to a fairly wide selection of chemicals, so if anyone knows what sorts of things are used for fire-eating or the like I would love to give it a try. Cheers. Jon.
