This is how to make my fave home made bong.

Place one melon in the freezer for around 15 to 20 minutes, don't forget it's there because it's a bastard to cut when it's frozen solid.

Cut off the top and hollow out the melon, watch your fingers with that knife. LOL

Using a stem pipe make two holes in the top.

Sieve the inside of the melon to get rid of the seeds add a little water and half fill the hollowed out melon , add some ice cubes too..

Push your stem pipes through the holes in the lid making sure one goes into the water and the other doesn't.

Make a third small hole in the lid (this will be your draw hole.

Place the lid on the melon, fill the bowl and get tokin'
Nothing to it really
