In this video I take a break from the heavy technical side of thermoacoustics to play with a giant propane powered singing tube. This is also called a Rijke tube, and you can find another great video explaining how they work from Bruce Yeany here: https://www.youtube.com/watch?v=hMf8Rn4bdME Also check out the other videos so far in my thermoacoustic series: Part one, thermoacoustic engines: https://www.youtube.com/watch?v=abswNCqnMRQ Part two, thermoacoustic refrigeration: https://www.youtube.com/watch?v=kkBBkQ8jFRY A special thanks to my top Patrons: LVE, Enzo Breda Lee, Jon Hartmann, TheBackyardScientist & Eugene Pakhomov!
