I got an energy cosmic ball as a present (it’s got two electrodes on it so that when you touch them both it completes the circuit and makes it light up and make an alarm noise). I also have a plasma ball. When I put them next to each other the energy ball made strange noises – and the noise changed when I moved it around (one note for one of the electrodes, and a different note for the other one, and when I made them touch it made an angry noise). BUT WHY? I know that if you hold a light bulb near a plasma ball it lights up, but why did it make the energy ball make strange noises not just its normal noise?
