If you are the type of stoner who enjoys building his/her own bongs and pipes then this is a good idea for you.
Materials:
1 Highlighter
1 square inch of tin foil
some electrical tape
A drill tool bit
thumbtack or needle
Take the highlighter and hollow it out. So pop the thing off the end of the hiighlighter and take out the ink. Then take off the cap and pull the actual marker out of the tube.
Once it is hollow wash the highlighter tube out thouroughly with hot water.
The take the tin foil and wrap it neatly around the wide end of the tube.
Then take some electrical tape and tape the tinfoil so its stuck on the wide end of the highlighter tube.
Then poke small holes in the tin foil. This is your filter
Next place the tool bit on top of the highlighter tube and grab some electrical tape.
Then wrap the electrical tape around both the highlighter tube and the drill tool bit so they are stuck together.
And you should end up with something that looks like this,
The filter/bowl
This can be used as a bowl for a homemade bong, or it can have an elbow put on it so it a pipe. The method also does not burn any plastic.
