if it turns out to be soap then this is by far the best way to smoke it
1. Take a ciggarete and remove all the moisture from the baccy by toasting it with a lighter (you'll have to keep it constantly moving to prevent the paper lighting up).
2. Empty this baccy in to a mix card and grind to a powder (as close to flour as possible) with your fingers
3. Take about a third of an 1/8 of the soap, and wrap it in a piece of tin foil so that it has a long bit of foil protruding to use as a handle.
4. Burn the pot in the foil until there's been a steady stream of thick smoke for 15 seconds or so (don't worry about the amount of smoke this seems to waste, the final product is worth it).
5. Empty this pot in to a 2nd mix card as soon as you remove the flame, and immediately crumble as finely as possible (this bit will hurt, sometimes a little, sometimes a fuck of a lot, but you get used to it).
6. Pour the contents of both mixcards through a sieve in to a third mix card, making sure it all gets nicely mixed up.
7. Take the chunks left in the sieve, give em another quick flame in the foil, fluff em up till their nicely powdery (doesn't matter too much as there shouldn't have been too much caught in the sieve if u did a good job) and add them to the mixture
This process should leave you with a powder almost the consistency of flour which is perfect to hit in the bong (the only way soap should be smoked). Whilst this may seem like a bit of an effort, it only takes 5 minutes or so and your puff will go twice as far (as well as actually lighting properly in the dish)
DONT DO THIS WITH PROPER HASH, ONLY SOAPBAR....IT WONT WORK AND WOULD BE A WASTE OF NICE GEAR
