Looking to maximize a small amount of weed? Make sure you try a gravity bong.

Gravity bongs work by creating a vacuum that first gathers smoke in a chamber. Then, once the chamber is full, the gravity of the water beneath the chamber pushes the smoke deep into the toker's lungs. The result? You get really stoned, really fast.

Check out the video above for step-by-step instructions on building a gravity bong at home. And remember, be careful when trying this at home.
