Its just my way of smoking hash.
OK so I call it a hot can and here is how I do it.
What you need is a empty can of pop and dry it out.
Then make a small whole on one side near the bottom and take off the pull thing at the top.
Next get a piece of card and a safety pin and insert through card.
Get a piece of hash, put it on pin and light.
Rest it over the whole in top of can and wait around 30 seconds.
Suck from bottom whole and enjoy.
I've included pics to help show what I mean.
