The Danish Youtube-канал Fysikshow pleases the subscribers with that creates various surprising devices, being guided by various laws of physics. This time talented children created a music visual analyzer on the basis of Bunzen’s torches which looks in operation very much impressively.
Bunzen’s torch is the injector gas torch developed by German chemist Robert Bunzen. In this project which authors christened The Pyro Board, are at the same time used 2500 such gas torches.
Cunning of the device is that submitting on metal tubes a sound of different frequency, founders of The Pyro Board managed to create in them zones of the increased and lowered pressure, why the flame escapes from openings with different force, creating on a surface surprising fiery patterns.
In video, located is slightly lower, you can see this device in operation, and also hear more detailed explanations from his founders as this device functions. There is open a safety issue, after all work with combustible substances always demands extra care.
Pyro Board: 2D Rubens’ Tube! Standing waves of fire! Check out Audible: http://bit.ly/AudibleVe Fysikshow: http://bit.ly/Fysikshow – I’m hosting Michio Kaku in Melbourne ONLY: http://bit.ly/VeKakuTickets Rubens’ Tube is an awesome demo and here we take it to the next level with a two-dimensional ‘Pyro Board’. This shows unique standing wave patters of sound in the box. The pressure variations due to the sound waves affect the flow rate of flammable gas from the holes in the Pyro Board and therefore affect the height and color of flames. This is interesting for visualizing standing wave patterns and simply awesome to watch when put to music. Thank you to Sune Nielsen and everyone at Aarhus for sharing this demonstration with me! And thanks for having me at your conference. Music by Kevin MacLeod, www.Incompetech.com "Ice Flow"
In the second video it is possible to see The Pyro Board work already under other musical composition.
The Pyro Board Sound waves are transmitted through a flammable gas creating alternating high and low pressure zones. This creates the flame pattern.
