1. I can see distorsion in the close-up, the picture jumps. So I think it’s either a projection, or a stroboscopic effect.
I think it’s filmed and then projected, no real liquid there.
But how to achieve the clearly three- dimensional projection, is beyond me.
I say, kill the witch!!
2. Someone there claims it’s not a strobe but it looks to me exactly like a strobe slightly out of phase with water droplets, giving the illusion they are moving upwards.
3. I’m pretty sure it has to do with static electricity.The crossed metal under the cans suggests this. A similar thing was done by Walter Lewin in an OCW lecture on electromagnetisme, (Lewin’s experiment produced visible and audible electric discharges using dripping water that was led through crossed.pipes to build up charge (if my recollection is correct).
4. Definitely a strobe. The same phenomenon that makes a spoked wheel seem to be going backwards, or forwards, or even not moving when it’s really going forward.
5. Its to do with sound waves played at a certain frequency. The oil is coming out on the can but a vibration being played at a certain frequency from the source of the oil gives the optical illusion that its falling upwards. You can find videos like this on youtube, where they do this or even make it appear that the liquid has frozen mid air.
6. if this is a trick with a strobe why does slowing the play back not destroy the trick? or watching out door during day time so my lamp is not flickering?
i see the drops go upwards no matter how i try to replay without strobe effect.
clever effect. i think we have not reached it’s proper description.
