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:


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

    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!
