Caltech posted video of a stable plasma torus, created by engineers using water and a dielectric plate: "lightning in a bottle, but without the bottle.
In addition, engineers working with the plasma noticed that their cell phones encountered high levels of radio frequency noise—static—while they were in the same room as the experiment. It turns out that the plasma ring emits distinct radio frequencies. "That's never been seen before. We think it's because of the piezo properties of the materials that we used in our experiments," Pereira says, referring to the materials' ability to be electrically polarized through mechanical stress—in this case, the flowing of water.
They've got no idea what it might be useful for, but have already filed a patent on the method for genereating the torus. Commercial proposal: a pretty random number generator to replace the lava lamps in Cloudflare's HQ.
This is amazing.

Our world is a colorful one, and when it comes time to repaint the house or create a new design, many of us look to our surroundings for inspiration. However, matching colors from the outside world to our canvas isn’t the most precise process when we’re just eyeballing it. The Nix Pro Color Sensor removes the […]
You probably remember the Twisty Glass Blunt since we love to write about it. And you may also remember its little buddy, the Twisty Glass Mini. Well, today we’ve got a fun surprise that isn’t so little. Less isn’t always more, and on those days when you need to decompress with a good smoke, the Twisty XL […]
