I used to have a Nerf gun that shot plastic darts and it had a laser pointer for sighting haha. That thing was dangerous, as my little sister got me in the forehead with one of the darts, and I must say that it hurt like a &$#*#%!
I had lawn darts. Those were cool. Had a mini-hammock also. Not sure if it was that brand. When someone laid it in you could grab and flip 'em over so they'd be locked in. That was fun.
Any list of dangerous toys without the slip-n-slide is not complete.
