With a neat physics trick, this desk toy levitates water droplets in midair

Add as a preferred source on Google

Whether it is gravity-defying phone chargers or human-floating tractor beams, we’re suckers for levitating technologies. A new Kickstarter campaign therefore hits our sweet spot with an “executive novelty” (read: a high-priced desk toy) that levitates water droplets entirely for your viewing pleasure.

Called LeviZen, the retro-styled device itself is crafted out of high grade walnut wood and precision-machined aluminum with the necessary audio technology to float drops of liquid using high frequency sound waves not audible to regular ears. It also boasts some in-built LEDs to make sure the water droplets are properly illuminated so as to look their best. No, it doesn’t have any practical applications, but it certainly promises to be an attention-grabbing conversation starter.

Unlike the majority of levitating gadgets we’ve written about in the past, LeviZen doesn’t use magnetic levitation to achieve its effect, due to the fact that this would not work with a liquid like water. Instead, it opts for sound-based acoustic levitation, which adds an unusual element to a product that’s joining a crowded levitating marketplace.

“With LeviZen, we want to bring the ability to levitate liquids by acoustic levitation to the masses,” a spokesperson for Simplistyk told Digital Trends. “Acoustic levitation is a complicated phenomenon, but to explain it in simple words, it is achieved by having two inaudible sound sources facing each other and outputting the same frequency at each other, which causes the waves to collide and form a standing wave. [As a result], we get the stationary nodes with high amplitude waves above and under them. This causes water to be trapped in the node sections.”

As with any crowdfunding campaign, there are risks attached to backing LeviZen. If you do fancy adding an extra gadget to your home, though, you can pledge money for a unit on Kickstarter. The inventors have already more than doubled their $15,000 funding target, with more than 40 days still remaining on the clock as of this writing.

The price set for a single unit is $199, which includes the LeviZen Liquid Levitating Machine, a power adapter with both U.S. and international plugs, and a custom liquid dispenser. Shipping is set for July 2018.

A new startup wants to fix the military’s working-dog shortage with cloning and gene editing
Promising pitch, plenty of unanswered questions about the dogs.

Military working dogs charge into places the rest of us would flee. So, I understand why anyone would want to breed tougher, healthier dogs for the job.

Warhound, a new startup from Colossal Biosciences co-founder Ben Lamm and Anduril co-founder Palmer Luckey, has stepped out of stealth with $200 million to clone and gene-edit working dogs for American troops, police departments, and emergency services (via TechCrunch).

AI can describe a picture, but it still struggles to understand blind users
A University of Maryland study finds that Be My AI often buries useful answers in lengthy descriptions, leaving blind users to work harder to get the information they need.

AI can describe a picture, identify objects, and answer questions about what a camera sees. But when a blind user needs a quick answer, getting an entire spoken essay about the scene isn't exactly helpful. Researchers at the University of Maryland (UMD) have found that AI-powered visual assistance can leave blind users doing too much work to get the information they actually need.

The study, titled Say It My Way: Exploring Control in Conversational Visual Question Answering with Blind Users, examined how people interact with Be My AI, an AI-powered feature of the Be My Eyes app. The researchers found that users often received lengthy descriptions that didn't adequately address their immediate goals, forcing them to ask follow-up questions or find ways to steer the AI towards a more useful answer.

Etsy cracks down on AI slop listings. Everyone else needs to take note.
Now every platform must decide what counts as handmade.

Platforms tend to shrug off AI clutter until it threatens what they sell. For Etsy, that thing is trust in the maker.

To protect that, Etsy has banned AI-generated how-to guides and listings made entirely by bots. Most sellers must show at least one unretouched photo of the item (via Etsy Seller Handbook).
