Daniel Harris, a junior student at Scarsdale High School, Scarsdale NY. Daniel is a student of chemistry teacher Elise Hilf Levine and art teacher Dina Hofstetter. With a high-speed camera Daniel was able to capture a great example of combustion. The valve to the lighter fluid — butane — is opened at the press of the red button while, the serrated hardened steel sparkwheel is rotated, generating a spark. Once the butane gas is ignited, the flame continues to burn as long as the valve is held open.
