The Knockout is a 5 in 1 attachment which turns any bottle into a beer shotgun, water pipe, gravity pipe, and a beer gravity pipe! This pretty crazy looking product is made with high quality food grade silicone and stainless steel, perfect in size to fit in a pocket to ensure one parties hard. They say- gulp the beer down and take the hit! Hip Hop Rapper, Snoopdog, has been all ga-ga about it.
