Get the GBmug. A device used by crackhead stoners, myself included, who do not have access to an actual bong. Using a socket and a bottle with holes burned through it, you pull the smoke in using the gravity of the water falling.

Get the GBmug. 
A double-action 9×19mm Parabellum semi-automatic pistol, manufactured by Steyr Mannlicher in Austria. The initial GB stands for Gasbremse (gas brake), a reference for its unique mechanism, gas-delayed blowback action. It was designed in 1968, intended as a homegrown replacement for older handguns in Bundesheer service. Its production was phased out in late 1980s as the Bundesheer decided to adopt Glocks instead.
