ok so it isnt actually invented yet, but heres my idea, drill a hole and attach a tube at the top of a big plastic bowl, at the other end of the tube is another bowl, attacked to a fan, which sits in your window blowing out, so you just keep your peice under the bowl, and take hits under the bowl and blow into it, and all the smoke will go outside, and theoritaclly you wont smell nearly as bad. i think that idea is tight as fuck, but im blazed so ouy guys tell me
why dont you just blow the smoke out the window and after you hit it hold the bowl next to the window or sploof it as previously mentioned.
