This toy blaster makes and launches softball-sized snowballs up to 50′, allowing rapid, long-range assaults during neighborhood snowball confrontations. Simply place snow in the forming chamber and close the lid, and it packs three perfectly spherical snowballs. To blast your mark, place one snowball in the muzzle, aim the launcher, and pull back the slingshot mechanism. Because the blaster is powered by elastomers instead of batteries, it provides uninterrupted, fast-action play. Made of durable, cold-resistant plastic. Includes targets for shooting practice. Ages 8 and up. 17 1/2″ L x 5 1/2″ W x 12″ H. (2 1/2 lbs.)
It just needs a laser

The Gun O’ Clock is an alarm clock that has to be shot in the bullseye with a toy laser gun to be turned off.
I love the idea. This is just what I need. I *often* turn my alarm clock off while still mostly asleep and then wake up late.

This is very cool. Fits in a pocket. Max range is 16 feet, more than enough for self defense.
And … can be carried through airport scanners. Build one before they are banned!
