joraemi,
Your story reminded me of a product that I saw a picture for not long ago (haven't seen the real thing yet) of some gas additive that comes in the same type of container, and has a similar-sounding name, as one of the energy drinks such as 5-Hour Energy. The store had put a large sign on the box of them that they were NOT CONSUMABLE, but you've got to wonder how many people either didn't bother reading that or forgot what it was later after buying it. I hope the smell was such that they didn't actually drink it at some point.
