It’s a collect them over time thing, IMHO. I’ve got a folder with a few hundred. I usually only use a few dozen often. But I have a few hundred. Also, if you can think of a moment from a show or film that would be great as a reaction GIF, use Google’s advanced search, drop box “animated” and someone else likely has made such.
We need this because reasons. This one’s for the coffee drinkers amongst you - British designer Joshua Renouf has come up with a coffee making alarm clock which can wake you up with a fresh cup of joe.
When a drop of liquid hits a solid surface, the liquid will do one of two things: flatten like a pancake or launch a halo of droplets into the air. It’s a surprisingly complex and difficult-to-predict event.
The secret is in the air. By taking into account the gas surrounding the drop, researchers find that they can calculate just how fast a drop can travel without splattering when it hits. A new study suggests that after the drop strikes a solid surface, a tiny cushion of air carries along its edge as it spreads. The air provides lift like on an airplane wing and flings away droplets from the drop’s edge.
