Isopropyl alcohol works well if it is of high purity (we use 96% I think). Methyl alcohol would be a really dangerous choice.

- dghughes 6y agoYes I'd certainly use isopropyl alcohol. I'm pretty sure I can get it with a purity of 95% or more at my local pharmacy. Dry ice is the other problem it's not something readily available in my town. I don't think regular ice is cold enough especially when using isopropyl alcohol which isn't as volatile as methyl alcohol (methanol).
