OMFG! Hahahaha! The series of events was hilarious!
That is one huge salmon!
This one is not a hoax. Biologist Doug Killam discovered and caught this gigantic chinook salmon in Battle Creek, California.
He was making a survey of recently discovered salmons in the area when he spotted this huge fish.
Holy shit, you can actually bounce a water in a superhydrophobic(whatever) surface!
Ok, I googled it. Superhydrophobic are materials that have surfaces that are extremely difficult to wet. So, the water will somehow resist this kind material.
Using a high-speed camera GE scientists captured the details of the water dancing on superhydrophobic surfaces in GE Global Research’s Nanotechnology lab.
Here is their statement:
Hello everyone, I have some exciting videos that I want to share with you! Using a high-speed camera setup in the lab, we can finally capture the details of the water dancing on these amazing superhydrophobic surfaces. We discovered that even when the surfaces had the same contact angle for stationary water droplets, their ability to resist the wetting of impacting droplets could be totally different. In the following three videos, the contact angles of a stationary droplet on all three surfaces are ~150 degree. When an impacting droplet (with the same impact speed) hits on the surfaces, the droplet can either stay on the surface.
Look at the way the water droplet spreads, recoils, breaks into satellite droplets, and completely lifts off… that’s what we really want for an impacting-droplet resistant surface! You might wonder what we can do with a cool thing like this? Imagine applications that involve high speed water droplets, such as wind turbine blade, airplane wing, or even just your car in motion. These are just a couple of the exciting possibilities that we are looking at.
Amazing stuff!
