Girl, 12, proves toilet water cleaner than ice

A Florida schoolgirl won top prize with a science project proving toilet water is cleaner than ice in fast food restaurants.

Jasmine Roberts, 12, of New Tampa, tested her thoery in five local restaurants, reports Tampa Bay's 10 News.

"My hypothesis was that the fast food restaurants’ ice would contain more bacteria that the fast food restaurants’ toilet water," she said.

Jasmine says at each restaurant she flushed the toilet once, then used sterile gloves to gather samples.

She also collected ice from soda fountains and asked for cups of ice at drive thru windows. She then tested the samples at a lab.

Jasmine said: "I found that 70% of the time, the ice from the fast food restaurant's contain more bacteria than the fast food restaurant's toilet water."

Her project won the science fair at Benito Middle School, and she hopes to win the top prize at a regional science and engineering fair.
