🙉 It took me far too long to realize why this cup filled to the rim & overflowed. I took it empty from the cabinet & pushed the middle button so it "should" have filled only half. Smh & lol. But there's cool physics here. (Btw, we use refillable k-cups for the environment.) /1
2/ See the interesting pattern in the coffee dust that leaked through the filter? This reminds me of asteroid impacts on the Moon because there are (what look like) primary and secondary impacts in this pattern.
3/ On the Moon, and asteroid hits at high velocity and blows out ejecta, which then strike the Moon at much lower velocities. Those are the secondary impacts. This drip pattern looks like a central impact site surrounded by places where the splashes went out and hit secondarily.
4/ So I tried to test this hypothesis by repeating the experiment with a video capture, but it didn't repeat the interesting results...
So I redid it using a finer grind to get more dust in the flow. It still didn't repeat the interesting pattern. And then I had run out of the house to meet family at Disney, so I couldn't keep trying. So here is a challenge with a prize...
6/6 The first person who tweets a video that repeats this pattern of a splash surrounded by little splashes in the coffee dust, and that adequately shows WHY it forms this pattern, will win the prize. I will mail you a @CLASS_UCF patch and a small meteorite. Any takers? 😅
