Bong water-pipe(preferably glass)
Herb of your choice.
Frozen water in cube form(crushed ice works too, but those are crushed-ice bonghits, which are a completely different thing).
Some type of fire.
Instructions
Fill clean bong with clean water.
Slide a few ice-cubes down the stem.
Fill the bowl area with cannabis.
Use a lighter, or other type of fire to burn the herb while you inhale through the stem.
