If you're going to blow your hands off tonight you may as well know the science behind it.

Americans are enthusiastic about the promise of science but lack basic knowledge of it, with one in four unaware that the Earth revolves around the Sun, said a poll out Friday.

The survey included more than 2,200 people in the United States and was conducted by the National Science Foundation.

Ten questions about physical and biological science were on the quiz, and the average score -- 6.5 correct -- was barely a passing grade.
