Watermelons are delicious and great fuel for kids on a hot summer afternoon. But they also might make great fuel for cars!
Wayne Fish, a chemist with the Agricultural Research Service in Lane, Oklahoma, and his team were working on a project using watermelons when they realized that watermelon juice could be used to make ethanol, which can be used as fuel for cars. Only about four of every five watermelons grown are sold to people for food. The remaining fifth of the watermelons go to waste. That could be a lot of fuel!
Read more about this green (or is it red?) fuel on National Geographic News.
