It works the same way a gravity bong does, just without water:
- Step 1: Load up the bowl
- Step 2: Holding the top plastic piece with one hand, light the bowl with the other
- Step 3: While lighting the bowl, simultaneously release the bottom half of the device, allowing it to fall towards the floor and stretch out the Caterpillar
- Step 4: With the Caterpillar filled with smoke and fully stretched, remove the bowl and breathe in the smoke. The caterpillar should shrink as you breathe in.
