This Tool Unravels Plastic Bottles Into Super-Strong Ribbon

Every hour, Americans toss 2.5 million plastic bottles in the trash. Instead of sending that plastic to a landfill where it will take hundreds of years to decompose, this tool allows consumers to transform their trash into something they can actually use. The Plastic Bottle Cutter features a built-in blade that can unravel any sized bottle into a super-strong ribbon of plastic, Gizmodo reports.

To put the tool to work, users cut out the bottom of a plastic bottle, slip on the bottle cutter, and start pulling the strand. The 5.5-inch, wooden tool can be adjusted to produce plastic ropes of different widths. The material it creates is strong and flexible enough to be used in a variety of applications.

In the video above, you can see the rope being used to make a rig to tow a car, but the ribbons can also be manipulated with heat to create unique decorations for your home.

After a week on Kickstarter, the project has already raised over $140,000 in funds, blowing away their initial goal of $9445. There's still plenty of time left to pledge and reserve a Plastic Bottle Cutter of your own. You can preorder the tool starting at $22 with delivery estimated for June of this year.

Air Quality in American National Parks and Big Cities Is Roughly the Same

National parks usually have more vegetation, wildlife, and open spaces than urban areas, but the two don't look much different when it comes to air quality. As City Lab reports, a new study published in Science Advances found that U.S. national parks and the nation's largest cities have comparable ozone levels.

For their research, scientists from Iowa State University and Cornell University looked at air pollution data collected over 24 years from 33 national parks and the 20 most populous metro areas in the U.S. Their results show that average ozone concentrations were "statistically indistinguishable" between the two groups from 1990 to 2014.

On their own, the statistics look grim for America's protected areas, but they're actually a sign that environmental protection measures are working. Prior to the 1990s, major cities had higher ozone concentrations than national parks. At the start of the decade, the federal government passed the Clean Air Act (CAA) Amendments in an effort to fight urban air pollution, and ozone levels have been declining ever since.

The average ozone in national parks did increase in the 1990s, but then in 1999 the EPA enacted the Regional Haze Rule, which specifically aims to improve air quality and visibility in national parks. Ozone levels in national parks are now back to the levels they were at in 1990.

Ground-level ozone doesn't just make America's national parks harder to see: It can also damage plants and make it difficult for human visitors to breathe. Vehicles, especially gas-guzzling trucks and SUVs, are some of the biggest producers of the pollutant.

India's Supreme Court Demands That the Taj Mahal Be Restored or Demolished

The Taj Mahal is one of the most recognizable monuments on Earth, but over the years it's started to look less like its old self. Smog and insect droppings are staining the once pure-white marble exterior an unseemly shade of yellow. Now, The Art Newspaper reports that India's Supreme Court has set an ultimatum: It's threatening to shut down or demolish the building if it's not restored to its former glory.

Agra, the town where the Taj Mahal is located, has a notorious pollution problem. Automobile traffic, factory smoke, and the open burning of municipal waste have all contributed to the landmark's increasing discoloration. Insects and acid rain also pose a threat to the facade, which is already crumbling away in some parts.

India's highest court now says the country's central government must seek foreign assistance to restore the UNESCO World Heritage Site if it's to remain open. Agra's state of Uttar Pradesh has taken some steps to reduce pollution in recent years, such us banning the burning of cow dung, which produces heavy brown carbon. In 2015, India's Supreme Court ordered all wood-burning crematoriums near the Taj Mahal to be swapped for electric ones.

But the measures haven't done enough to preserve the building. A committee led by the Indian Institute of Technology in Kanpu reportedly plans to investigate the exact sources of pollution in the area, a process that will take about four months. The Supreme Court plans check in on the status of site every day from July 31.

Air pollution isn't the only factor damaging the Taj Mahal. It was constructed near the Yamuna River in the 17th century, and as the water gradual dries up, the ground beneath the structure is shifting. If the trend continues it could lead to the building's total collapse.
