Did some photo experiments with detergent in water with a 405nm, ( says <5mw), pointer with a cut gem style amethyst crystal as a target. Thought I'd share them.
Hope you liked them, please forgive quality still learning how to work with the camera. :undecided:
I have tried suspending a crystal in regular drinking glasses, wine glasses, Pyrex dishes , etc and have gotten nice results using water, olive oil and some other liquids. The beams coming out of the enclosures look the best, keep on shooting
