The Lime Bomber is designed specifically for this purpose: inserting lime slices in your bottles. It consists of two parts: a “loader” that sits on top of a bottle and a “plunger” you push down into the loader. You place the loader on top of your bottle of beer, drop a wedge of lime into the loader, push down on the plunger, and tada! Lime in beer.

This could come in handy as a way to impress your friends at a party, but also in bars, since some areas seem to have a law that prohibits handling the lime without tongs or gloves.

How much under $29.99?
