Neurons are the basic building blocks of the nervous system. These specialized cells are the information-processing units of the brain responsible for receiving and transmitting information. Each part of the neuron plays a role in the communication of information throughout the body.
There is 850,00 rubber bands in the current world's largest rubber band ball. That certainly is a lot!!
With 400 rubber bands and a large watermelon you can demonstrate the difference between potential and kinetic energy by exploding a watermelon with rubber bands. You probably want some goggles to protect your eyes. Place a bunch of rubber bands around the middle of the watermelon. Be careful though as all that pressure from the outsite will start to explode the watermelon. Rubber bands are a great example of potential energy. Potential energy is energy that is stored up, not being used, just waiting to be unleashed.
