4. Gravity Bong
Ah, gravity. The force that keeps us grounded–and can also get us really high. Gravity bongs are essentially devices that use water and air pressure to build up a lot of smoke and then force it into your lungs.
It doesn’t use up a huge chunk of your stash, and better yet, you can make your own following these easy steps and using materials that are probably already in your home.
Of course, if you’re not the crafty, innovative type, you can find a pre-made gravity bong online or in your local smoke shop.
