Catapult Boy Ring sling-shot rubber band shooter

Apliance Studio has designed this Catapult Boy Ring which is also same like Sling-Shot camera but, it doesn't have a camera. The Catapult Boy ring is unlike any other in that it actually has a secret use that isn’t immediately apparent! What looks like a simple ornamental ring is actually a clever device for shooting rubber bands “sling-shot style” at your friends. Just keep a pack of rubber bands handy and you’ll be popping everyone all day. [Source]
