Just bought Mystic smoke. http://www.penguinmagic.com/product.php?ID=S11460
It works...but jeez...the smell is absolutely disgusting. Easy to use, but the smell and residue is absolutely putting me off.
I also bought it and I totally agree. It smells horrible, and is very sticky and hard to get off. Not very practical either. At least it was cheap,right(?). haha
Ah, the smell brings back so many memories of middle school...lol,
I never used this stuff for magic. Always just to annoy people, it is the most hilarious thing ever. We (Me and my friend) nearly filled up my entire Social Studies classroom one time, it was ridiculous and hilarious!
I don't think it's good for magic at all, it makes your hands sticky and nasty, and the smell is "bad" (though I've grown to like it, smells like burnt...something).
Anyway, just have fun with it.
