In the beginning there was the bottle bong... and today it is quick and easy with the handy 'Uni-Bong' bottle adapter:
Just fill a standard screw-cap bottle with water or a liquid of your choice, screw the 'Uni-Bong' adapter onto it, insert the glass chillum and the clock strikes 4:20!
If you like, you can of course add a carb hole to the bottle!

Please note: bottle not included!
