Look at what happens when Mozart catches fire!
What I love most about the video is their reactions. And the physics of course.
The story of the experiment was first posted in February, 2010. Preston and Jake continued their research into pressure, sound and waves. This video from May 2011 is the result of that Independent Study. I understand that it was conducted after considerable planning and research, with the approval of parents, thorough attention to safety issues (ventilation, fire etc.) and with the guidance of engineers.
Or, as in this case, a cool experiment during vacation.
This is a first attempt at creating a Ruben’s standing wave flame tube showing the relationship between sound waves and air pressure. It looks quite hazardous and not to be tried at home without guidance, permission and precaution.
