found this in 30 seconds on google, who knows if it works or not though
Here what I did,
Scratch off the yellow coating
Then with a sharp pair of scissors cut the pill in half and realized it was incased in a plastic like shell, I took the scissors and carefully removed the plastic shell
(trying to lose as little of the actually pill as possible in the process)
Then "shaved" the pill into the smallest pieces possible into a spoon
Then heat (NO water) it will melt down and start turning to a golden brown "goo" in the spoon
Once it is all completely melted down, added 2 1cc syringes full of water and continued to heat until it was all mixed with the water
Then just throw in your cotton,(or micron filter if you actually have these)
And draw it all up, add a little cold water or give it a minute or two to cool
And slam!
