In this video guide I will show you how to win a live grenade in a slot machine. Now first off you won't be able to get this until you get the ship in space. Once you get this far there will be cut scenes and a mission for checking on everybody. Once all that is done head to Moxxi's bar. You will see slot machines along side the left wall. Just hit all the ones that cost money and you will probably get a bomb flying out at your face. The achievement will pop once the grenade comes out of the machine.
