Let's have a battery-charged electric shaver.
At first let's start it without the covering, and take a look at it!
And next...
Let's start with the covering on it!
What happens?
Second time, it turns around 4 times faster.
But why does it turn around?
Milkovic-effect?
What do you think?

  • Now try it in a round floating tub. use blue-tac to stick it to the base. it may or may not do the same?

    Vibrations are used to lift grains, granules etc. up an incline, against gravity.

  • THX for your visit!

    I am going to try it this way!

  • ohh q gran video¡¡¡ debio costarle una fortuna fabricar esa maquina para demostrar ese efecto de porpulsion inercial¡¡¡

  • I think the increase in precession is more so due to the added weight of the cover...

    I think I might have missed the purpose of this video, though. :/

  • that's gyroscopic precession. The electric motor in that thing is basically a gyro but it has a small rotor, the added rotors when attatching the clip might be what's responsible for the increase in precession.

  • The frequency of the vibrations is greater imo. Just from the sound itself u can hear the pitch is different.
