Scientists Discover Foam Discourages Drink Spillage

I love millennial scientists.

As much as I desperately want revolutionary battery life and cures for diseases, it’s always great when an experiment comes from a bar and Starbucks.

For Emilie Dressaire, assistant professor of mechanical and aerospace engineering at the New York University Polytechnic School of Engineering, inspiration came in the form of a latte, and for Alban Sauret, researcher at the French National Center for Scientific Research, it was a Guinness.

Both, along with several colleagues, had noticed and were intrigued by the damping effect foam has on beverages and how that facilitates carrying them.

In a paper recently published by the American Institute of Physics and co-authored by François Boulogne, these researchers discovered that foam (from your latte or a stout) minimizes sloshing. By carefully adding one layer of foam at a time, they saw that five layers of foam (15mL or 3 teaspoons) correlated with less movement from the liquid beneath it by tenfold.

More foam didn’t have a significant effect on the liquid sloshing, nor did foam in the middle of the glass. The foam clinging to the sides of the glass are what dampens sharp movements from the liquid.

While this has larger implications for the way we transport substances like fuel, we’re more concerned with not spilling hot coffee all over ourselves and not looking like sloppy drunks on our third sixth eighth beer.

Physicists Launch Burger and Fries into Space to Promote Delivery Service


While the majesty of outer space is as breathtaking as TV describes it, there’s no reason to send a perfectly good order of burger and fries up there. Well, other than to appease invaders. Physicists Peter Sharman and Andy Shovel also own a burger delivery business based in London. They thought it would be a good idea to send their burger into space.

The duo behind Chosen Bun successfully launched a burger and chips (fries) 112,000 feet above the ground. The meal was attached to a rig with a balloon the size of a two-bedroom house, according to the Telegraph. The pair also fitted a GoPro camera onto the structure in order to properly document the historic occasion.

Upon its return to Earth, the burger was discovered (intact) 32 miles from where it was launched. It definitely wasn’t edible. The chips, however, were lost during the descent and are presumably gone forever.

It cost Sharman and Shovel £2,000 ($3,212 US) to pull off this stunt. While this wasn’t the first burger to be launched into space, it was the first combo meal. This attempt also went farther and higher.

Check out the astounding video below.
