This is from another forum for your information..
Essentially it is the same theory behind hexane hash except you use a different substance that leaves no residue, requires no cooking after, no terrible taste, no harmful side effects just minor precautions, creates pure 100% pure THC. Pure Liquid O2 is that secret ingredient.
What I will be creating is a canister that can hold the clippings as well as a multiple silk screens, and a final collection area. Obtaining the O2 is no problem I work with it every day and have access to a complete private area as well as all of the correct couplings to make it flawless and perfect. Facts about liquid O2: Due to its cryogenic nature, LOX can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid oxygen.oxygen's temp −183 °C. Within seconds rapidly turns to gas and has no evidence of being there.
So since the liquid 02 is so cold and under so much pressure 150 psi essentially it should separate the THC from the plant matter and break it down through the screens within a matter of seconds or minutes.
I have attached a prototype I will slowly begin working on and hopefully through carefully stoner engineering, we will be able to reach a new level of stoned.

edited to add, there was a bitmap image with his post but unable to upload it. Its just a flash cafetiere with 6 or so fine mesh filters in it.
