This machine pulverizes glass bottles, turns them into fine-grain sand in just 5 seconds

How do you dispose of a bottle of beer once you’re done drinking it? You crush it into fine-grain sand, right?

Well, thanks to a smart new promotion created by New Zealand brewers DB Breweries — working alongside the ad agency Colenso BBDO New Zealand — it’s possible to do exactly that.

“Two thirds of the world’s beaches are retreating as people across the world use non-renewable beach sand for construction, roading and other uses,” Simon Smith, brand PR and digital manager for DB Breweries, told Digital Trends. “We had some [conversations] over beers, and came up with an idea to crush glass bottles into a sand substitute that can be used in things such as construction, roading, even golf bunkers; meaning that we can keep our beautiful beach sand where it belongs: on our beaches.”

New Zealand, Smith said, has a pretty impressive recycling rate, although there’s always room to do more. To that end, DB Breweries has built several machines able to take empty bottles and turn them into substitute sand. All a drinker needs to do is deposit his or her bottle in the machine, which then uses miniature steel hammers to crush it into 200 grams of sand in only five seconds — after extracting the plastic labels with a vacuum system.

“Our sand will be processed through a screener which sorts it into a fine grades between 1.1 – 0.4mm particle sizes,” he continued. “Over the next few months, we’ll be creating up to 100 tons of sand, which is the equivalent of 500,000 DB Export Bottles. The resulting sand substitute will then be given to our construction and retail partners to use in place of beach sand.”

The ultimate goal is to provide a way of prompting people to recycle by giving them an image of what exactly it means to do so, rather than leaving it as an abstraction. “Our ambition for the campaign is for people to have something tangible to think about, such as the love of our beautiful beaches, as a reminder to recycle,” he said.

Hey, if it means we get to drink and save the planet, who’s losing out? Aside from our liver and bank balance, that is…

Anti-surveillance clothing is getting cheaper, but don’t expect an invisibility cloak
Affordable shirts now claim to confuse facial recognition, although their protection depends heavily on the camera and software watching you
Chart, Plot, Adult

Anti-surveillance clothing is starting to look less like an art-school experiment and more like something you could actually wear outside. Shirts designed to confuse facial recognition systems now cost about as much as ordinary streetwear, although buying one won’t make you disappear.

The Guardian reports that designers are using face-like prints, unusual cuts and infrared lights to interfere with computer vision. These techniques target specific weaknesses, so their success depends on what happens to be watching you.

This spinning drone hides in plain sight using a visual illusion
This drone doesn't turn invisible. It tricks your brain into thinking it has.
Phantom Twist

For decades, engineers have chased the dream of an invisible drone. The usual approaches have involved transparent materials, camouflage coatings, or complex optical systems that bend light around an object. Researchers at Northwestern University decided to take a completely different route. Instead of hiding the drone itself, they chose to fool the human eye.

The result is Phantom Twist, an experimental drone that spins so rapidly it almost disappears into the background. It's not technically invisible, but to anyone watching, it looks more like a faint blur than a flying machine.

This smart knitted fabric can flip switches, count your steps, and even change shape
Grandma's knitting just entered its Iron Man era

For most of us, knitting brings to mind sweaters, scarves, and perhaps an ambitious grandmother determined to make winter more fashionable. Researchers at Harvard University, however, have a far more futuristic vision. They've transformed ordinary knitted fabric into a programmable material capable of changing shape, acting as an electrical switch, sensing movement, and potentially forming the foundation of tomorrow's wearable technology.

The research, published in Advanced Functional Materials by scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), demonstrates how machine-knitted textiles can "snap" between multiple stable shapes without relying on motors or rigid mechanical parts.
