This demonstration utilized 900 mousetraps that were set-up for a chain reaction. It took 4 people 7 hours to set up the traps! As far as we know there has not been a similar reaction at this scale. The demonstration visualizes how nuclear fission, Newton's Laws, and potential and kinetic energy work. Learn more and try some experiments at http://www.sciencebob.com.
