Erin enjoys performing Irish dance, swimming, and doing various arts and crafts. Her future career aspiration is nursing. Erin says, "I think it's a great job because you get to help people and make a difference in the world."
Inspired by the swimming pool in her backyard, Erin wondered why pool water sometimes turns people's hair green. Pool water typically contains two chemicals that Erin considered prime culprits: chlorine, which acts as an antibacterial agent, and copper, which comes from antifungal solutions or copper coils that heat the pool. She hypothesized that copper, and not chlorine, can give hair a green tint.
Erin collected bunches of hair in four different shades from a local hair salon. She separated the hair into three groups, soaking one in an algaecide solution, another in a chlorine solution, and a third that received no treatment. Only hair soaked in the algaecide turned green, confirming her hypothesis. After testing various household chemicals on the green hair, she found that lemon juice best removed the unwanted green tint.
