According to the article, there was a poison symbol on the label. What kid is so dumb that they see a skull and crossbones and go ahead and consume the contents?
Heck, when I was little, I knew not to consume random stuff, especially if it had skull and crossbones on it. My sister, who resented having a baby brother, even tried more than once to get me to drink stuff from under the sink when I was around 3 or 4 yrs old, but I knew enough to not do it and that the skull and crossbones on some of those bottles meant it'd kill ya.
Maybe kids today don't know what that symbol means? They have, after all, removed lots of the violence from cartoons, whereas when I was a kid, you learned from cartoons that if it had skull & crossbones on it, and you drank it, you died. If it had POISON on it, you died. If you got shot, you died. If you played with dynamite, you died (yes, not that long ago it was easy for an individual to buy dynamite). If you got stabbed, you died. If you fell from a high ledge, you either died or ended up with lots of broken bones. So, perhaps we have the cleansing of the cartoons and keeping kids swaddled until they're 21 to blame? Sure, the cartoons did a poor job of explaining what death is, since they showed the characters becoming ghosts or being alive in the next cartoon, but nonetheless. . .
