Blizzident is a custom-made, 3D printed, whole-mouth-at-once toothbrush that claims to be able to clean your teeth in six seconds. It uses a mold of your teeth, lined with "a dense field of tailored bristles" that work with an integrated tongue-scraper and floss to conduct what appears to be a thorough scraping, brushing, and flossing of all the significant mouth-surfaces.
It's expensive -- there's the cost of a scan or impression (up to $200), then $300 for a brush that lasts a year (replacement brushes are $160 thereafter). But as high as those prices are, I'm rather taken with this: the prices are sure to come down -- 3D-printed anything costs too much, thanks to soon-to-expire patents that slap a ~5000 percent markup on the plastic, and scanning just keeps getting cheaper. And while the normal two minutes' brushing time isn't much, but if you brush twice a day, every day, and can effectively zero that out, it adds up. Plus, I'm always in favor of something that replaces an error-prone, mindless task with an automated system that takes the errror out.
All that said, there's every possibility that this just doesn't work. The company doesn't list any peer-reviewed, independent studies evaluating the efficacy of their gadget. But presuming it does work, and presuming it comes down in price to something like $50, I'd buy one -- two, even, so I could keep one in my travel-bag.

Samsung claims to have developed an “Ultra Thin Glass” for its new Galaxy Z Flip foldable smartphone, signalling scratch resistance and durability beyond that of similar products. But tests conducted by Zack Nelson using a Mohs Hardness Testkit [Amazon] — a set of styluses made of different materials — show that it is no more […]
There is very little evidence that Ring reduces crime. Hundreds of police departments have signed agreements with Amazon-owned Ring to obtain access to the home surveillance camera footage. Interviews with many of them, in 8 different states, show little to no evidence that Ring actually deters criminal activity.
Whether you’re managing a political campaign or building a client base, there comes a time when you stop seeing people and start seeing numbers. This doesn’t happen suddenly. You shake hands, make calls, and build relationships. And then those relationships disappear into a database of donors or customers as your organization grows. People get brought […]

Prep your precious babe for success by starting them early with the world’s lightest balance bike, the Brilrider FLIGHT.

With so many advancements in modern society, you’d think we’d have moved beyond the butane lighter by now. A pressurized, flammable gas, butane fumes can irritate your eyes and skin, can elevate your heart rate, and even lead to cardiac arrest. And we did mention that whole highly pressurized and flammable part, right? While certainly […]
