How does the Hydra Lamp Anti Gravity Water Drops thing work?
In: Technology
The lamp releases water drops at a regular rate. Its light flashes on and off very quickly, so fast that you can’t even see it. The flashes are timed such that drops have fallen to a point just slightly above the drop locations at the previous flash.
What looks like a single drop rising from the bottom to the top is an illusion created by a series of many different drops captured by the flashes of light.
Stroboscope lighting. A drop is dropped every x seconds. The light actually flashes, it’s not continuous light, its just so fast that you dont see it with your eyes.
So if the light manages to “flash” every time the drops thatbare falling reach the exact same point in the air, it would look like the drops were hovering mid air. Since your eyes and brain mainly see the image where the light flashes “on”.
Now if we were to slow down the lighting flashing speed every time the light flashes on, the drop would have a little more time to travel thus making it seem like the drop would slowly go down.
If we were to speed up the flashing light, the drop would seem to go upwards. But what we’re reall seeing is actually the snapshot of the next drop falling down but being “snapped” slightly higher than the last one. This cycle repeating constantly makes it seem like it’s going up when in fact you’re just seeing a snapshot of the next drop but slightly higher than the previous one.
The bright light flickers to create the effect. Basically the water is falling down, but the light turns off and then back on just in time for you to see the next droplets just barely above where the last one was, etc.
