"Pray for Coal"
Here's an article entitled Pray for Coal, about the ten most dangerous toys of all time. Those of us old enough to remember will not be surprised that lawn darts, or "Jarts," head up the list. (A friend of my brother's used to be an outright maniac with them Jarts, it's a wonder we never got speared.) I also like the nifty item— from the 1950s, of course— which one of the commenters over there calls the "Johnny Science™ Home Cyclotron"— yes, complete with genuine uranium.
And there's lots more over there, check it out.
