After being prompted to create a product for Grandview’s entrepreneur program, the boys came together to research the electro-receptivity and electro-sensitivity of sea life and ultimately concluded that cartilaginous fish like sharks and stingrays can perceive natural electric stimuli. With additional brainstorming, the rising high school students hypothesized that magnets could be used to activate and confuse their electroreception and essentially deter these animals from a magnetic field.
The boys created arm bands made of magnets in neoprene…
