Got creative the other day with a little flashlight. Sorry about the picture quality. Here's what you'll need: 1 Flashlight similar to: And one metal screen from a cheap pair of earphones: How does it work? The head and rear of the flashlight screw off. Push the battery out of the chamber with an object such as a key. Pull out screen that was contoured to the inside of the chamber. Flip screen so it is laying flat and wedge it into the chamber. This is your bowl. Notice how the flashlight is still actively functioning when put back together. Best part of all is that the ends of the flashlight that screw off are rubber sealed. No smell, no one will ever know it is a pipe. Have fun; be safe!
