A ray gun that fires actual arcs

A rechargeable, gun-shaped Tesla coil that throws a visible electric arc from the tip and lights a fluorescent tube through the air. There's a voltage meter on the side and a gold-plated panel on the front. It's a science demo with a trigger. Keep it away from phones, pacemakers and anyone who hasn't agreed to be in the room.

Grow mushrooms that glow
in stock

Grow mushrooms that glow

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.

Stand behind it and vanish
low stock

Stand behind it and vanish

A lenticular sheet three feet by two, on handles. The lens smears whatever's behind it sideways, so somebody standing back sees a stretched wall instead of a clear view of you. You don't vanish. You blur, and at ten feet against a plain background that's enough. No tools to assemble.

A speaker where the bass is visible
in stock

A speaker where the bass is visible

A small Bluetooth speaker with a sealed vial of ferrofluid in front, and an electromagnet that makes the black liquid jump and spike in time with the music. Four colors of backlight. The sound is a single 5-watt driver, so this is a visual product first. Nobody's buying it for the audio.

Touch the glass, catch the lightning

Touch the glass, catch the lightning

An eight-inch glass globe with a gas mix inside and an electrode in the middle, so purple streamers reach out from the center and follow your fingertips on the glass. It reacts to sound too, and it's plug-in, not battery. The same object that's been in science museums since the eighties, now on a nightstand.

Eighty-three elements, sealed in acrylic
in stock

Eighty-three elements, sealed in acrylic

An 8 by 5 inch acrylic block with a sample of 83 real elements set into the grid, each one in its own cell under the symbol. The radioactive ones and the gases you can't just cast in plastic are left out, and the listing says so. It's the periodic table as an object instead of a poster, and it's heavy enough to feel like it should be.
