what you will need
1 drinking glass -must be glass
1 straw
1 lit joint/blunt

before you spark the j, wet the glass under the tap and place in the freezer for atleast 45 to make it frosted. start smoken the bone, take a huge hit in your mouth but don't inhale it, blow it VERY SLOWLY through the straw into the glass, and it will fill up with milky smoke. use the straw to inhale it.

if your good with giving shotguns you should be able to fill up a glass for someone without using a straw. great party trick, standing there handing out glasses of smoke. the smoke only lasts for a few seconds, but it's usualy sucked up before it dissapates.
