Today one of my HL classes was doing the required experiment about measuring EMF and internal resistance of a battery. Having mastered the skill of using the multimeter Sven Herman decided to measure the resistance of Sophia's hair. I can't remember what it was but it was measurable at least. Sven's hypothesis is that it was due to the conditioner and suggested it must have been elorial (as in electric). The product in question is actually L'Oreal but that wouldn't be funny would it.
