Hard Science's video: How Chemicals Change Your Voice - Hard Science

WATCH OUTTAKES HERE: http://testu.be/LxkMDB Michael Thurber from cdza teaches Tara and Anthony to become instant musicians with the aid of gaseous chemicals! Experiment Tips: - After completing the experiment, be sure to take a couple of deep breaths to ensure you get all of the sulfur hexafluoride out of your lungs. - Do not inhale too much of either gas, sulfur hexafluoride and helium are not a substitute for real oxygen and can suffocate if over-used. List of Materials Used: - Helium - Sulfur hexafluoride - Balloons - Voice/Singing skills Helium Info. http://en.wikipedia.org/wiki/Helium Helium's boiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions. Speed of Sound: Liquids vs Gases http://www.le.ac.uk/se/centres/sci/selfstudy/snd3.htm The speed of sound is higher in solids and liquids than gasses because gasses are less stiff than liquids and solids, and stiffness is the most important factor. Stiffer the material, the faster the sound will move through it. High fives to our special guest Michael Thurber of cdza! http://www.cdzamusic.com Special thanks to the Jewish Community High School of the Bay (www.jchsofthebay.org) and to our Science Advisors: Kishore Hari (www.bayareascience.org) and Marc "Zeke" Kossover (www.kossover.net) Join Anthony Carboni and Tara Long as they turn the world around them into a giant science experiment.
