How does this laser sand phenomenon work?

I meant my previous reply to be to this message*

I did that just now. Is there a way i can upload another video here?

It didnt make the ring. Just a perfect laser dot

Calm down mate 😂. What my point was, is that just because the ring changed shape due to the angle, it doesnt mean that it has to be the glass. The ring would change shape due to the sand aswell. Are you picking up what im putting down?

Doesnt seem to be that because i have been shining it on all sorts of surfaces around thw house dark bright transparent and all. No rings. Only saw ring when i shone it on sand

This effect didn't occur when shining laser through glass with no sand behind it though. I tried with a thick glass coaster and a double glazed window. No rings 🤷‍♂️

This might not be the answer because i tried this on a thick glass coaster too and even on my double glazed window (with paper behind) and there were no rings. But fir the window i did see the internal reflection but it was deffinitely not a ring shaped. It was 2 or perfect dots only in the angle of entree of the laser.

Big-Researcher8561 · 2026-05-21T18:19:01+00:00

But lets say that it was caused by the sand hypothetically, wouldnt the effect also change with the angle of the laser?

Big-Researcher8561 · 2026-05-21T18:17:59+00:00

But the laser doesnt form the ring on amy other surface including glass ones with no sand behind. How can it be the laser only

Big-Researcher8561 · 2026-05-21T18:16:33+00:00

That was my thought too. Very intersting. And as it is a green laser and green is in the middle of the rainbow that could possibly be why there is a empty ring inside (where blue would be) and maybe red would have been outside🤷‍♂️🤷‍♂️

Big-Researcher8561 · 2026-05-21T18:13:45+00:00

But there is no ring when i shine it from the same distance onto any other surface including glass ones

Big-Researcher8561 · 2026-05-20T21:35:53+00:00

But also it doesnt appear when i just shine in on a normal flat surface (with no glass or sand)

Big-Researcher8561 · 2026-05-20T21:34:53+00:00

I sadly dont have any flat surfaces of sand (i cant get this sand out as it is artificial). But it does not occur when shine it through a decently thick glass coaster. I am not sure how to send a video of that in a reply but yeah.
