they don't go into much(any)detail as to how they did this, but did give the ingredient list..part of which i had to do a double take on..
"To create a single liter of oil, Nexcel used 180 pieces of chewing gum, half a liter of used fryer oil, one gram of silicone sealant, 14 batteries, one liter of used engine oil and -- my favorite part -- one old Christmas tree."
so,in a little more digestible format-
To make 1liter of oil, they used:
180 pieces of gum
1/2 liter of used fryer oil
1 gram Silicone Sealant
14 Batteries
1 liter of Used Engine oil
1 Christmas tree.
so, to make a liter of oil...you start with a liter of oil...then throw a bunch of stuff in it...
I know it's way more complicated than that, and yes, it makes sense, just struck me as odd...
