The MAV Besty Bong is made for two people and maximum cooperation. Step one is to figure out how the hell to fill the ice-catch and then maybe you're really going somewhere. Obviously, this bong has two mouthpieces which mean you are going to need a friend to get this thing ripping and roaring.
We recommend hitting this bong gently at first and trying to equalize the pressure between the two mouthpieces before ripping the bowl. It takes some practice to hit this water pipe just right but that is half of the fun!
