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.

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.

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.

Agitation during freeze also has a notable effect of the density and optical properties of water ice.
Might be worth a shot

Not knowing much about the topic, but would some of these larger crystals make some sparkly effects if shattered?

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.

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)."

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.

Cool crystal “trees”
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.
