  • Story:

    A student, preparing for a triathlon, suspected that the 45 minutes each day
    she spent training in a chlorinated pool was damaging her nail polish. She
    wished to investigate whether the color of the nail polish might make a difference.
    She mounted acrylic nails on sticks and polished them with two different color nail polishes. She soaked them together in a chlorine solution equivalent to a swimming pool’s chlorination and then tapped them 100 times on a computer keyboard to simulate daily stress. The response is the % of nail chipped off as measured by scanning images of the nails and using an image processing program.
