This is the most common method. Get a spoon and mix 2 parts of cocaine hydrochloride (regular cocaine) to 1 part baking soda in some water.
Heat solution gently (with a lighter or candle) until white precipitates form, and stop heating when precipitation stops.
After gentle heating, the freebase cocaine will float to the top, any excess soda will settle on the bottom.
Collect the compound that rises to the top, and you have the finished product, ready to use.
What you're trying to do is start and sustain a chemical reaction (bonding the hydrochloride with the base-soda) so as long as the reaction is happening you don't have to continue heating.
theres chemistry and physic some were in there
