As it’s the season for all things festive and frosty, why not have a crack at a bong that guarantees an ice-cold smoke?

But at the same time, it’s a hell of a lot more fun than building the same tired snowman with hilariously detailed body parts to tick off the neighbours. Don’t deny it…you know you do.
