Ok so this is REALLY trippy… get stoned with some good weed, get a strobe light and a blowup matress with an automatic pump. Lay on the already blown up matress with the strobe light on, let all the air out and experience the magic. Then if your pump is strong enough, while laying on the bed fill it back up. Trust me, this shit is fun! (make sure its really dark so the strobe light works well)
