Two separate photos taken in complete darkness, on right is a standard camera flash at lowest setting triggered by the sound of the shot. On left is
the pellets hitting a sugar cube wall, the only light is being emitted is by triboluminescence which shows the shadow of the pellets as they strike.

That's a very interesting idea! I wonder if it would work to a lesser extent with water ice? I read somewhere that ice also exhibits
triboluminescence. With such a strong pulse, even ice could show up. Lightning in a storm cloud is also related to ice formation.chloric1 - 3-10-2024 at 03:13
This is why I like to visit this forum on my 65 inch smart tv! Your picnic acid looks like a magical crystal crop on some far flung planet on the
edge of the universe. Reminds me, I really need to make some sodium chromate from my dichromate so I can use it for barium testing along with Epsom
salts.Morgan - 3-10-2024 at 08:08
Perhaps a solid perfectly fused plate of sugar would produce a brighter or different light show over pressed cubes?

Thats actually a decent idea, I hadn't even thought of ice. I wonder if doping the solution before freezing can change its effect. I did have some
large chunks of ZnS that I planned to try, probably still sitting around somewhere. They are doped with something (gold?) and phosphorescent, you'd
expect a change in the wavelength between phosphorescence and triboluminescence which is mostly the result of nitrogen excitation. Rainwater - 3-10-2024 at 10:53
Agitation during freeze also has a notable effect of the density and optical properties of water ice.
Might be worth a shotMorgan - 4-10-2024 at 09:25
Those large crystals are actually pretty cool. I can't really predict what it would look like. Since it's photographed with an open shutter it'll
capture all light that's created. Transparent crystals may just give a glowing ball or they may crack and highlight the fissures I really don't know.
Pessimistic me is betting on the glowing ball though.Morgan - 5-10-2024 at 08:52
Perhaps a powdered metal additive would be another long shot to try.
"Sugars contain many electron-rich polar groups, such as aldehyde and hydroxyl groups. When sugar comes into contact with a metal conductive layer,
the volatile electrons of the metal can gather at the sugar surface, which can increase the output power of a triboelectric nanogenerator (TENG)." Sir_Gawain - 14-10-2024 at 17:07

Nice picture! This looks like the best one since Hyakutake. Interesting that the dust tail is in the opposite direction of the ion tail.
It is pretty spectacular; the tail spans nearly 20 degrees. I was really surprised that this photo picked
up the antitail.

This is the result of my byproduct of distilling nitric acid from potassium nitrate. It was wet slush at 7 am this morning and I was going to try to
dry it with suction filtration and isopropyl alcohol rinse. But I came home to an alien landscape! Going to let it do its thing for a few days.
