Using Fire to Display Sound Waves
Monday, October 9, 2006 at 8:02PM I'm not typically a supporter of fire based experiments being conducted in one's garage, but this is quite cool. The "scientist" here appears to be a high-school or junior college professor. He demonstrates a home made Rubin's tube. This device demonstrates sound waves through the use of fire. With many small holes drilled into a piece of PVC, a small speaker and some propane.
This is actually quite cool.
