Now, Pahlavan and his colleagues have figured out what stops the puddle - forces acting at the nanoscale. Such precursor films have been observed for puddles that expand out completely to a thin flat sheet - the so-called “ complete wetting” case - but they can’t explain puddles that spread a short distance and then stop (partial wetting). One popular solution is to assume that a thin microscopic film coats the surface ahead of the puddle. There’s something missing here,” explains Amir Pahlavan, a graduate student at MIT in a press release.Ĭlearly, puddles do spread, so physicists tweak their model to explain why. “Within a macroscopic view of this problem, there’s nothing that stops the puddle from spreading. The calculations instead imply that the forces at the puddle’s edge would be too strong to allow spreading at all. Gravity pulls liquid down and spreads the puddle, while surface tension, where the molecules hang tightly to each other, makes droplets bead up.īut whereas the classic model can be used to explain the final shape of a puddle, it doesn’t explain how the puddle started spreading in the first place. Using the classic model, physicists would describe liquid spreading as the result of a “competition between gravity and surface tension,” Choi writes. Researchers from the the Massachusetts Institute of Technology have the answer, reports Charles Q. But if a glass of wine spills on a (hypothetically) perfectly flat countertop, what keeps the puddle from spreading out forever? Until now, physicists’ description of fluid flows couldn’t really account for why puddles stop. Aris also plays other games on a regular basis, such as Grand Theft Auto V, Call of Duty: Black Ops, Dark Souls, and Resident Evil 7.Sloppy, muddy puddles created by summer rainstorms owe their boundaries to the dips in pavement or ground. He streams under the name “AvoidingThePuddle” on Twitch, where he currently has 384k followers. He struggled with the controls from the beginning and ended up crashing into another plane and he ended up killing himself and being apprehended.Īris is a Tekken streamer who also plays other games on a regular basis. When he used the plane’s gun, the streamer was taken aback.Īris seemed impressed with the built-in gun, but he forgot that this was his first time flying in Warzone. While anti-aircraft guns can easily take down planes, Aris found himself crashing into another plane while attempting to fly one. Players can use them to move quickly around the map, track enemy locations, and engage in dogfights. As part of the Warzone Pacific update, planes were recently added to COD: Warzone. When the streamer was driving around in his jeep, he came across an airplane and decided to try flying it. After figuring out the controls, he attempted to fly the plane but was killed when it collided with another plane.ĭuring a recent live stream, Aris was in the middle of a COD: Warzone match. The streamer had never flown a plane before in-game and struggled to even use the mounted gun at first. During a recent COD: Warzone stream, Twitch streamer Aris Bakhtanians AKA “AvoidingThePuddle” had a hilarious mishap while attempting to fly an airplane.Īris was driving around while playing Call of Duty: Warzone when he spotted an airplane.
