I'm thinking that this is a great example of defective design
I don't design children's toys. But if I did, I would suspect I shouldn't cover my toys in a substance that turns into roofies.
Unfortunately the small Aqua Dots are colorful and just the right size to be candy. The covering of the dots metabolizes into a drug often referred to as the "date rape" drug. It causes the children become confused, then suffer lose of muscle control.
I know, I know: our "broken" tort system might result in the maker of Aqua Dots being sued out of existence, thus depriving children of other wonderful products, such as the forthcoming "draino dots" and "My Li'l Methlab."
