I don't see the issue really... It's one of those things that I've seen just about everything that goes into this effect (the type of device it is.) even the chemicals... never in a million years will I have any clue how the two and two work. We already know it's a mixture of organic chemicals anyway... the description says so... I think it's good to know that it leaves a taste and smell... that's something I wish I would've known about Frozen.
