I tried it a few times. Every time was pretty much the same. First you get this feeling like there's a bunch of tiny needles pricking you (but it feels kinda cool), then you start laughing your ass off. Everything feels really, really heavy. My buddy tried like 40x his first time through a dry bong, and no shit he wasn't even speaking a coherent language. Everything he said was like "halablab abababa", then he said "charlie looks like a brick of mountains". So have fun with it!
