    Mesmerising Proof That You Can Make A Droplet Of Liquid Levitate

    Fluid dynamics ftw.

    If you put a droplet in an ultrasonic field, you can make it levitate.

    Increasing the acoustic pressure flattens the drop.

    And by changing the strength of the field, you can turn it into a star with different numbers of points.

    The higher the field strength goes, the more points the star gets.

    Until it all gets a bit too much.
