Rubens tube
A Ruben's tube is like a magic tube that can turn sound into fire. Inside the tube, there are tiny holes on one side and fire coming out of the other. When you play music or make loud noises in front of the tube, the sound travels through the holes and amazing patterns of fire appear on the other side.
It's like how when you blow air into a balloon, it gets bigger because the air spreads out inside. Similarly, when the sound goes through the Ruben's tube, it makes the air inside move around in a special way that causes the flames to dance and change.
It is important to note that Ruben's tubes should be used under adult supervision and with proper safety precautions since fire can be dangerous if not handled properly.
