There are only so many times you can allow a coworker or roommate take your sandwich. The first time it could have been a mishap, the second could be coincidence, but any more than that and you’re looking at a hostile that needs dealing with. While actual violence would be of no use (and pretty pointless, especially over a sandwich), a little playful revenge isn’t going to do anyone harm, right?

The iPhone Controlled Ball Dropping Bomber will come from above, where they never would expect it. This is a little RC helicopter that is controlled through your iPhone or iPad that will drop a table tennis ball onto your enemies. It will work indoor or outdoor at about 30′ away, and the free app uses the built-in accelerometer to control the bomber’s movements. This is a rather expensive toy that will cost you about $130 if you’re interested.
