I suppose virtually everyone has played some sort of game in school (and I don’t mean board games). In my case, there was coin football and water guns, but I know that if we had discovered the Mini Rubber Band Artillery back then we would’ve had a blast.
You can shoot rubber bands with your hand, of course, but it’s just cooler to have a special gun for it. At least it makes it easier to stage wars. Tip: if you get two or more guns, you can connect them and, when you turn a crank, they all fire. Your enemies will cower in fear! (or retaliate, in which case… sucks to be you, I guess.) Also suitable for offices – play with your friends or torture annoying co-workers.
How much under $29.99?
A lot: $1.99 for one gun on ThinkGeek.com.
