Screw pipes, make a bong! Take a bic pen, a socket, and you could use the screen from a sink, or cut out part of your window screen. Then cut the tip and end of the pen off and put whatever you're using a filter over it, then put the socket on top of all of that, so that the socket is holding the filter on top of then pen, then tape it all together. Then all you need is a water bottle, pack a bowl on the socket, and make a slice in the bottle.

It's not nearly as hard as you'd think
