I just tried this and it didn't work, like nothing happened. To those who got this to work: how long did you hold the lighter under the weed. Also are you supposed to hold your finger over the choke and the end of the pen while the bulb fills up with smoke? And if you are do your fingers get hot, cause I was pretty high and thought it might get hot so I wore my dad's work cloves and held them shut hahaha

And to sean140, I know this thread is old but the salt takes the white shit off the bulb. Or you could just use a "white light" light bulb like I did and skip that step...
