Grow mushrooms that glow

Bioluminescent mushroom culture

A syringe of Panellus stipticus culture, a wood-rotting mushroom that glows faint green in the dark. You'll need a substrate, patience, and a very dark room; it's dim, and the photos online are long exposures. This is a real cultivation project, not a novelty. For someone who already grows things.

A pyramid of uranium ore

Sold to people who own a Geiger counter and need something to point it at. The ore fluoresces under ultraviolet light and reads hot enough to prove the instrument works. This is a specimen quantity, the amount the rules allow to ship. Shelf, display case, cloud chamber. Not the nightstand.

Powder plus water equals blue light
in stock

Powder plus water equals blue light

Two powders, a beaker, and water: mix them and the beaker fills with cold blue light for a few minutes. It's the reaction inside a glow stick, unpackaged, with enough material for five runs. Classrooms buy it. So do people who want one thing on the counter that's real chemistry.

The top spins without touching anything
in stock

The top spins without touching anything

No batteries, no cord, no trick past magnets arranged so the top hovers above the base while it spins. Launching it takes a few tries and a flat surface. Once it goes, it stays up a long time, and everyone walking past has to stop and look.

A windmill that runs on light

A windmill that runs on light

Four vanes inside a sealed glass bulb, black on one side and silver on the other. Put it in a sunny window and they turn, with nothing touching them. William Crookes built the first one in 1873, and the physics of why it spins was argued over for decades after. It needs light, not batteries, and a flat surface where it won't get knocked over.

Blood shows up blue in the dark

Bluestar is the luminol that forensic teams actually use, and this is the training version: eight tablets, dissolve in water, spray, and old blood glows blue-white without total darkness. It is sold to labs and students. Where you point it in your own house is between you and your conscience.

One thousand pieces, all pure white

One thousand pieces, all pure white

No picture. No edges to sort by color. Nothing but shape, so the one strategy everybody skips on a normal puzzle is all you've got. The pieces are micro sized, so the finished board comes out smaller than the ordeal implies. The maker named it Pure White Hell.
