Hey guys this is a tutorial made from Theebomb1080 purely. If you want to use this tutorial on another site please ask me for permission.
A waterfall bong is often used with a 2 liter or a sobe bottle. I personally like the sobe bottle one better.
What you need: -A 2 litter bottle YOU WILL NEED THE LID (or sobe bottle; anyone will do)
-A lighter
-A rubberband (Not needed but helpful)
-A small amount of tinfoil
-A pen, pencil, pin, nail (anything that will make small holes).
First thing we must do is make the bong. So lets begin...
Step 1: Take your plastic bottle or sobe bottle and make a hole in the bottom of the bottle about the size of a pencil.
Step 2: In the middle of the cap of the bottle cut a hole.
Step 3: Poke holes through the tinfoil with whatever sharp object you're doing. (The smaller but more holes they are the better I personally think). However, make sure you leave enough room for the weed to sit on top. A rubberband around the tinfoil on top of the cap does help but isn't necessarily.
Congratulations, we've now made the bottle! Even Dak could get this far in the tutorial.
Now we need to know how to use this device we just made.
Step 1: Go ahead and put your finger over the hole you made on the bottom of the bottle. Make sure that the hole is over something like a bucket, bathtub, sink, bowl...whatever it may be so water can pour out of the bottle into it. Now, while holding the hole feel the bottle up with water from the top.
Step 2: Go ahead and screw the cap back on and place the weed on top of the tinfoil. (Make sure you don't sneeze or breathe heavily of that weed may just fly away also don't tighten it to the point it'll be hard to get back off). Go ahead and bust out your handy dandy lighter and burn that weed up! Keep it burning and go ahead and remove your finger blocking the hole on the bottom and let that water flow. While the water is rushing from the bottom of the bottle the smoke from the top is heading to the bottom.
Step 3: OH SHIT SON! See all that smoke inside of there? Go ahead and remove the cap.
Be CAREFUL though it might be hot.
Step 4: After all of that you'll have that big bottle full of all that compressed smoke. Go ahead and put your mouth over the top of the bottle (the cap should be removed already) and SUCK IT but please be careful all that sucking could create a blackhole.
Hopefully this picture will help you.
