Bandil, swim has done heaps of balancing chemical equations, not he would like something useful in his academic arsenal, not just the "Recipe" knowledge, but the whole chemical equation.
It's just very difficult to work out the equation from scratch especially when you don't know what the contents of say Iodine Tincture, or the contents of Pseudo Ephedrine HCL containing pills.
It's just an attempt to push swims knowledge boundaries.
Swim's not a tweaker, he's just an avid chemistry student.
