In this video I have some fun with an awesome battery life-hack using some alkaline batteries. I show you how to tell if a battery is charged or not just by how high it bounces! First, I weigh some batteries before and after discharging them in order to see if the weight changes. Then I talk about what changes inside of a battery and what makes it bounce like it does! I was careful to discharge them slowly so I didn't have a battery explosion like in a hydraulic press!
