Back in the 90s we discovered strontium aluminate - the most powerful glow-in-the-dark substance there is, as far as we know. It is easy to make as a powder, but almost impossible to grow as a crystal, and a friend of Gems of Science(@AngryTurtleGems) spent 13 years of his life figuring out how. The powder is opaque, so shining a light at a vial of it only ever charges the surface layer. Light goes right into a crystal and charges the whole thing, and it stays visible for days in the dark. They have only ever grown nine of these crystals. Gems of Science funded three of them. Go check out Stephen and Tim at Gems of Science: https://t.co/lsuyDcKnSz
Balloon-powered robots! 🎈
Surely one of the coolest and craziest robot project I've seen this year.
Buoyant Choreographies by RoMeLa is a fun art project shown at ICRA in Atlanta last year.
It uses special robots made from helium balloons and moving legs that float and walk around.
People can play with the robots using touch, game controllers, or even by blowing air.
The robots react by changing colors, moving differently, and showing emotions.
@DennisHongRobot, that's so cool, what's next?! 🤯
Here's the paper behind it: https://t.co/jDQESthPvS

They long, tedious grind of documentation and guides is almost over. This is definitely the most exasperating part of creating tools. I'm not going to wait for long form video guides to release this as that could push it out weeks more and most people won't need them. Trying to get to a minimum viable release asap!
