Carlsberg Is Ditching Plastic Rings by Gluing Its Six-Packs Together

The humble six-pack is an environmental nightmare. Those familiar plastic rings are notorious for the danger they pose to marine wildlife, as animals often get ensnared in them, starving to death when they get their mouths caught. While the common solution is to ask consumers to cut up the rings before placing them in the trash, that’s only a stop-gap measure. Now, Carlsberg has come up with a new plan to rid the world of plastic rings altogether. According to The Telegraph, the Copenhagen-based beer producer has come up with a glued six-pack design that keeps beers together without adding extra plastic.

The Snap Pack design keeps beer cans together with dots of glue. The bonds are strong enough to withstand the jostling of transport, but not so strong that you can’t break them apart. (Unlike the thicker plastic holders used by craft beer companies, which can be a nightmare to use.) The design took three years to perfect.

Previously, a Florida-based brewery called Saltwater created an edible, compostable set of six-pack rings designed to make drinking beer a bit more dolphin-safe, but this eliminates the rings entirely. Considering that Carlsberg is one of the world’s top beer producers, the environmental benefit is pretty dramatic. The company estimates that the glued packs will reduce the amount of plastic used in traditional multi-packs of beer by more than 75 percent, saving around 1322 tons of plastic every year.

The Snap Packs will make their debut in the U.K. in September 2018, before being rolled out to the rest of Europe and the world.

How to Build an Igloo, According to a Canadian Film From 1949

Centuries before you started building snow forts in your backyard, the Inuit had mastered using snow as construction material. This 1949 video, produced by the National Film Board of Canada (and with narration that uses some outdated terminology), illustrates how exactly people native to the Arctic can erect warm, temporary homes using nothing but a knife and the snow beneath their feet. The artifact was spotted by The Kid Should See This.

The igloo (or iglu in Inuktitut) in this footage takes around 90 minutes to erect, but a similar structure can be built by a skilled person in as little as 40 minutes. To put together the shelter, the two men carve up firm, packed snow into blocks that are about 2 feet tall, 3 feet wide, and 4 inches thick.

After the first row of blocks is placed in a circle on the ground, the builder slices a section of the blocks to create a slope. Each row that's placed on this foundation will spiral upward, creating a shape in which the blocks support their own weight. By the time the keystone block is fitted into the top, the igloo is strong enough to support the weight of a man.

The final steps are carving a doorway out of the bottom of the structure and plugging up the cracks with additional snow from outside. Even on a frigid Arctic night, the temperature of a well-insulated igloo can reach 40 degrees above the temperature outside. And the warmer the igloo gets over time, the stronger it becomes: The heat from the Sun and the bodies of the inhabitants melt the outer layers of the blocks, and that water eventually freezes to ice, giving the home more insulation and structural integrity.

If you aren't ready to build an igloo, here are some less intimidating snow projects to tackle this winter.

Charge Your Gadgets Anywhere With This Pocket-Sized Folding Solar Panel

Portable power banks are great for charging your phone when you’re out and about all day, but even they need to be charged via an electrical outlet. There's only so much a power bank can do when you’re out hiking the Appalachian Trail or roughing it in the woods during a camping trip.

Enter the SolarCru—a lightweight, foldable solar panel now available on Kickstarter. It charges your phone and other electronic devices just by soaking up the sunshine. Strap it to your backpack or drape it over your tent to let the solar panel’s external battery charge during the day. Then, right before you go to bed, you can plug your electronic device into the panel's USB port to let it charge overnight.

It's capable of charging a tablet, GPS, speaker, headphones, camera, or other small wattage devices. “A built-in intelligent chip identifies each device plugged in and automatically adjusts the energy output to provide the right amount of power,” according to the SolarCru Kickstarter page.

A single panel is good “for small charging tasks,” according to the product page, but you can connect up to three panels together to nearly triple the electrical output. It takes roughly three hours and 45 minutes to charge a phone using a single panel, for instance, or about one hour if you’re using three panels at once. The amount of daylight time it takes to harvest enough energy for charging will depend on weather conditions, but it will still work on cloudy days, albeit more slowly.

The foldable panel weighs less than a pound and rolls up into a compact case that it can easily be tucked away in your backpack or jacket pocket. It’s also made from a scratch- and water-resistant material, so if you get rained out while camping, it won't destroy your only source of power.

You can pre-order a single SolarCru panel on Kickstarter for $34 (less than some power banks), or a pack of five for $145. Orders are scheduled to be delivered in March.
