Must Watch: Ethyl Alcohol ‘Whoosh Bottle’

I’ve seen ‘whoosh bottle’ experiments before but never quite like this. Whether it’s the shape and contour of the glass bottle he used or the grade of ethanol (or a combination of the two), or something else, this is one of the best ‘whoosh’ demos out there. Watch:


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

    I wonder if lighting it at the top rather than dropping a match in has something to do with the smooth burn down the inside of the jug.

  2. That’s a good observation – I didn’t think of that. I wonder why scientists who demo this prefer matches to stem lighters – because this technique looks so cool!
