Does anyone else do this? While taking a hit cover your bowl with something that won't burn (I use my sharpstone grinder) forming a loose seal. It gives you huge hits compared to non covered hits.
Sometimes, plus it prevents excess smoke from escaping if you're trying to be sneaky and helps extinguish the bowl.
I'll try and let you guys know what happens Usually I just hit it hard enough so no smoke trails away
I cup my hand over the bowl pretty often when I use a pipe but that's because it's windy as shit usually and I have to block that somehow.
it can help but if your using a plasictic ligher you could be burnging plasctic into the bowl, use a coin
I cover it with my thumb after I take a hit, never thought about doing it while taking a hit Sent from my iPod touch using Grasscity Forum
i sometimes do it if i see an uneven burn, seems to correct it sometimes...i also thumb the bong when i pack a largerthanaverage bowl for us and were gonna share...
