Ok i have a vape but im gunna make a waterfall bong. First question, are they good?2nd. How do i use them?

[crudemood]

they will get you soooo fucked.
second.
you have the lid of the bottle where the bowl will be then fill the bottle up with water and let the water fall out with a hole at the bottom of the bottle. while holding down the flame to the bowl and the water will do the rest

Also, if you want to make a waterfall bong that also filters, get a realllly long stem. And then you just have this beautiful chamber of portable filtered smoke.
You know what would be cool?
For a party or something, get a couple ounces of weed, some helium and some whippets.... Fill a shitload of balloons up with all three...
Then turn on the strobe and electronica...
