Watch a Ping Pong Ball Rip Through a Soda Can at 500 MPH

Anyone who has ever played a spirited game of ping pong knows that the plastic balls are relatively fragile. But those delicate spheres can do some serious damage—when turned into 500 mph projectiles. In a new video (above) from Tested, hosts Norman Chan and Kishore Hari are joined by Zeke Kossover from the Exploratorium in San Francisco for an experiment involving a ping pong ball, a soda can, and a device called a "vacuum cannon."

The reason ping pong balls don't hurt when they're thrown is because of air resistance. As Kossover explains: "The ping pong ball, for its size, has a lot of air resistance. They're about two and a half grams, and they're fairly large for two and a half grams, so the wind resistance slows them down super fast. Even if you were to hit it at 60 miles an hour, by the time it gets to the other side of the table it's only going about 10 miles an hour." The key to getting the ball to move faster is to remove air from the equation, which is where the vacuum cannon comes into play.

After sealing each end of the cannon's tube with mylar sheets, Kossover draws the air out of the tube with the vacuum, then punctures one end so that air is allowed to rush back in. According to Kossover, that leads to about 45 pounds of force pushing on about two and a half grams (.00551156 pounds) of ping pong ball. In other words, it's a whole lot of energy barreling toward the unsuspecting aluminum can.

The Most Searched Shows on Netflix in 2017, By State

Orange is the New Black is the new black, at least as far as Netflix viewers are concerned. The women-in-prison dramedy may have premiered in 2013, but it’s still got viewers hooked. Just as they did in 2017, HighSpeedInternet.com took a deep dive into Netflix analytics using Google Trends to find out which shows people in each state were searching Netflix for throughout the year. While there was a little bit of crossover between 2016 and 2017, new series like American Vandal and Mindhunter gave viewers a host of new content. But that didn’t stop Orange is the New Black from dominating the map; it was the most searched show in 15 states.

Coming in at a faraway second place was American Vandal, a new true crime satire that captured the attention of five states (Illinois, Kansas, Massachusetts, Minnesota, and Wisconsin). Even more impressive is the fact that the series premiered in mid-September, meaning that it found a large and rabid audience in a very short amount of time.

Folks in Alaska, Colorado, and Oregon were all destined to be disappointed; Star Trek: Discovery was the most searched-for series in each of these states, but it’s not yet available on Netflix in America (you’ve got to get CBS All Access for that, folks). Fourteen states broke the mold a bit with shows that were unique to their state only; this included Big Mouth in Delaware, The Keepers in Maryland, The OA in Pennsylvania, GLOW in Rhode Island, and Black Mirror in Hawaii.

Monthly Internet Costs in Every Country

Thanks to the internet, people around the world can conduct global research, trade tips, and find faraway friends without ever leaving their couch. Not everyone pays the same price for these digital privileges, though, according to new data visualizations spotted by Thrillist.

To compare internet user prices in each country, cost information site HowMuch.net created a series of maps. The data comes courtesy of English market research consultancy BDRC and Cable.co.uk, which teamed up to analyze 3351 broadband packages in 196 nations between August 18, 2017 and October 12, 2017.

In the U.S., for example, the average cost for internet service is $66 per month. That’s substantially more than what browsers pay in neighboring Mexico ($27) and Canada ($55). Still, we don’t have it bad compared to either Namibia or Burkina Faso, where users shell out a staggering $464 and $924, respectively, for monthly broadband access. In fact, internet in the U.S. is far cheaper than what residents in 113 countries pay, including those in Saudi Arabia ($84), Indonesia ($72), and Greenland ($84).

On average, internet costs in Asia and Russia tend to be among the lowest, while access is prohibitively expensive in sub-Saharan Africa and in certain parts of Oceania. As for the world’s cheapest internet, you’ll find it in Ukraine and Iran.
