Ok, this was disappointment for even the 3 bucks I spent. I was at my magic shop and one of my friends were messing with it outside, so curious I asked what it was and he showed me where it was, and next thing I know I bought it. Major mistake to use it at club. It was like putting on too much Magicians wax, you just can't get it off. Once you think it is off after standing at the sink for 10 minutes it seems to just reappear. Though it was fun for the first 30 seconds of playing with it, it was not worth the $3.

This deserves half a star only because I got the knowledge to never buy it again.

jhm1953 you were much too kind on this review. I rate it worse.

First, it doesn't produce smoke. It is a sticky chemical that when you rub your fingers together, it throws thin strings of the substance in the air that sort of might look like smoke. Second, it is a sticky chemical, you will need to wipe your fingers off with a wet towel when you are finished. Sometimes it works better than other times, I couldn't always get it to work. I was disappointed, and am still looking for a better way to produce smoke when doing a trick. This one just wasn't the one for me.
