i don't even need to score it to break the top of the glass off, just pointing the laser above the liquid line will do that. that's a good idea to try cutting or at least breaking glass under water though

2025-01-16 19:15:39 +0000 UTCpointing it at the cap punches a hole through it, but pointing it below the cap but above the liquid line causes the glass top of the bottle to pop off. i don't even need to score it, it just breaks off on its own with the laser pointing in one spot

2025-01-16 19:14:25 +0000 UTCIf you get a diamond glass cutter from the store for like $3 and pre-score a line around the glass, will it follow the line better or still explode? How about try to cut a piece of glass under water? Does the water vaporize? You can cut glass with scissors underwater, thats why I ask. Maybe it will have some weird effects. Dang that is bright though wow... oof.

2025-01-15 18:43:46 +0000 UTCSooo what happens if you focus just on the bottle cap? Or, score a line across the neck and hit it with the beam. Might just crack it and off the top comes. Either way this is a wicked amout of energy on the bottle. Good experiments.

2025-01-15 18:23:13 +0000 UTCDoesn't look like a cut. Looks like a pressure explosion due to absorbing heat that cannot be transferred between molecules fast enough. I wish there were more references on photonic heat transfer. I have an experiment of similar focus on a catalyst in open air-water and am not sure if I am generating hydrogen (hissing indicative of pressure) that instantly reforms into water vapor with the oxygen it just split from or if its just vaporizing water that condenses fast. I am certain I am generating significant watts of photonic power that is not being absorbed by the water or the catalyst.

2025-01-15 17:44:53 +0000 UTCWow. Did it seem like the laser did more to cut the glass, or heat the contents? Or a little of both?
