334 m/s is a room installation, which is meant to visualize the speed of sound (c = λ ⋅ ƒ), which is about 334 m/s. two translucent tubes are filled with propane gas, which is set on fire to cause a chain reaction. a flame is burning from one side to the other, slowly accelerating to the point where it hits the end of the tube. due to the ratio of the gas-oxygene mix the flame there causes a rapid explosion, which can be heard as a sonic boom.
