This Time Lapse of Ice Cream Melting is Totally Mesmerizing

 

Watch ice cream melt into technicolor puddles—and then reform, as the film rewinds. There's something very satisfying about watching melted vanilla get sucked back into its chocolate casing.

What's neat about these melted ice cream scoops is the amount of diversity in colors and textures. Each scoop has a different color syrup, sprinkles, and sometimes glitter. As the ice cream melts, it creates a marbled waterfall of sugary, glittery cream. 

So what's going on when ice cream melts? 

First, a high school science refresher. Whether something is a solid, liquid, or gas depends on how much energy it has. Water vapor has a lot of energy (molecules moving very fast and far apart), while ice has very little (molecules moving slowly and close together). Energy (heat) likes to travel to places where it's needed, so if you put an ice cube in the sun, it absorbs energy and eventually melts and becomes water. On the flip side, if you put water in a freezer, the energy leaves the water to enter the colder space and the water freezes. 

Why does ice cream melt differently? 

As you might have noticed while eating a Mr. Softee cone, regular ice cream melts much more quickly than ice. Ice cream has a lot of fat in it, which is what creates the tasty treat's richness, taste, and texture; it also plays a big role in how fast the ice cream will melt. Low-fat ice creams have a lot more water and therefore need to absorb a lot more energy before melting. 

It's also worth noting that ice cream is not frozen solid like ice cubes are. Sweeteners lower the freezing point and keep the substance from freezing into a hard block. As a result, the ice cream melts differently. Layers of melted cream slide off because it reacts more quickly to the heat.

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.

Can You Figure Out Why the Turtles Bulge in This Optical Illusion?

Ready for a little vision test? Akiyoshi Kitaoka, a Kyoto-based psychologist who studies visual illusions, created this eye-bending image that appears to bulge and bend. In the image, shared on Syfy.com, the horizontal and vertical lines actually run straight across and down, but they look like they ripple, and the shapes (Kitaoka calls them turtles) look like they’re different shades of gray, even though they’re an identical color.

As Phil Plait explains for Syfy, the key is in the corners—the turtle “legs,” if you will. “At each vertex between turtles, they form a rotated square divided into four smaller squares," he writes. "Note how they're offset from one another, giving a twist to the vertices.” If you zoom in closely on the image, the lines begin to straighten out.

The difference in the colors, meanwhile, is a result of the contrast between the black and white pixels outlining the turtles. If the outlines of the turtles were entirely black or entirely white, instead of a combination, the grays would look identical. But the contrast between the two fools your eyes into thinking they're different.
