That's pretty fucking hilarious.. I actually had one of those "sky dancers" when I was little, though (I know, so girly), and yes, seeing it on the list made me laugh. I did hurt myself many times with that thing. (Mainly from sticking my finger into the hole and pulling the string, curiousity struck me... But I did piss my sister off a few times using it as a "gun" against her, which, surprisingly, was rather painful... They shoot ridiculously fast...)
Though, children can pretty much hurt themselves with anything you give them. They're just that stupid.
