here's another kirby art i finished last year of the Kirby 64 cast! complete with good and bad ending variants :3
this was a lot of fun to make, since Kirby 64 is one of my most favorite kirby games!
Left: A 100+ year old medicine bottle that my parents dug up in their backyard when I was a kid. Their house is built where the old municipal dump was in the late 1800s, so there were lots of bottles like it buried in the dirt. Right: An ordinary wine glass from the 1990s. Both of these things have been sat on a shelf gathering dust for over a decade.
...Until recently, when I got my hands on a UV flashlight.
[Video description: The bottle and wine glass described above sit next to each other on a table, with the bottle on the left and glass on the right. They are lit from above by a normal incandescent bulb, though the bulb is out of shot. There is a plastic squeaking sound, and the light dims and turns off, leaving the screen dark. There is a click, and a UV flashlight turns on off screen, to the left. Under its light, the bottle glows yellow-green, and the wine glass glows blue. The light holds for a few seconds, then turns off with another click, leaving the screen dark until the video cuts out.]
They glow!!! (These two aren't the only ones either, just the ones with the brightest color.)
There are a lot of different things that can be mixed into glass to make it fluoresce under UV (including, perhaps most famously, uranium). After doing some research, I think I've pinned down these two.
The bottle has manganese, which was (ironically) used to remove the green tint from glass and make it colorless.
The wine glass has lead, which increases the reflectivity of glass to make it more sparkly (and can also leach off into your drink and give you lead poisoning. Whoops!)
As I'm sure you can tell I've been nerding out over this big time. I love when science is pretty :)
