History

My Project/Demonstration came to existence in 1905 by a prominent figure in quantum physics, Heinrich Rubens. he was born in Germany in 1865. He later worked on some of the groundwork for Quantum Physics with other well known Physicists such as Max Plancks at the University of Berlin. The Ruben’s Tube, or Flame tube, was first demonstrated in 1905. The original Ruben’s Tube/ Flame Tube was a four meter section of pipe that had 200 holes, evenly spaced, drilled into it. The ends of the tube were then sealed and the flammable gas was pumped into it. The building pressure would then only have one route to equalize and when introduced to any loudspeaker of sorts, waves could be seen forming in the ignited flames flowing through the 200 holes pierced into the metal pipe before.

Ruben’s tube is based on Bernoulli’s principle.

“Gas flow is proportional to the square root of the pressure difference between the pressure outside of the tube and the pressure inside of the tube.”

The tube is a four meter section of pipe that has 200 holes, evenly spaced, drilled into it.

The ends of the tube are then sealed and the flammable gas is pumped into the tube.

the gas that leaks out of the perforated holes is lit.

The building pressure within the tube will then only have one route to equalize and the standing waves will create points with oscillating (higher or lower) pressure and points with constant pressure.

When introduced to any loudspeaker of sorts, waves will be seen forming in the ignited flames flowing through the 200 holes pierced into the metal pipe.

Where there is oscillating pressure less gas will escape and the flames will be lower due to the sound waves.

At the pressure nodes the flames will be higher
