Pyro Board or how the fire speaks back to you

Take an AC voltage supply, a loudspeaker, a pyro board, some inflammable gas and a little ingenuity and you get your self a nice sounding fire breathing music station with cool visual effects. This nice experiment has been done by Fysikshow, from YouTube.

The sound waves are transmitted through the flammable gas and create high and low pressure zones. Because of this you can see very interesting patterns unfolding before your eyes. When playing music and not some random sound it makes a very nice light show. The music used is : “The Signal” by BertyCox. Enjoy. Via [Geeksaresexy].
