MAYBE this is an allergy or something, but the box told me I'd get a pleasant 'tingling sensation'. They did not say 'using a two or three in succession will destroy you. You will run screaming to the bathroom to try and remove the demon-liquid, and find that it is SOMEHOW WATERPROOF. You will be in pain the next day, and walk like a complete dickhead for a while.'

This happened a while back, but the memory still haunts me. What the hell do the 'heating' ones do? Fry it?
