Ok so this might not be the greatest first thread but anywho here goes.
This requries a joint with a filter
two people
and a flat wall like surface
The person who is recieving the wall toke is to cruch down with thei back against the wall. Hyper ventilate for about 2 minutes. Close your eyes.
At this point the other person gives them a shot gun as the takee slowy moves up the wall with their eyes closed. The slower you go the better the blast. Keep your eyes closed and the smoke in your lungs til you can't hold it anymore and then open your eyes. Kaboom Enjoy
