There is a neat paper in this issue of the journal Lab on a Chip. The Tuteja lab out of Michigan developed a clever way of making droplets using a laser cut jig and an open platform. I mean literally open (not like open source). They make water in oil droplets that float across the surface of a hydrophobic chip. It reminds me a lot of the beer sphere.
I caught this image of a beer sphere suspended on its surface tension on the surface of a glass of beer. It was so persistent that I was able to get my camera and come back to the table to take a picture.
The Slo-Mo guys got really good footage of surface tension droplets. It’s an interesting phenomenon. Surface tension prevents a water droplet from merging with the water surface. If you have an oil surface, the water will not merge at all. Surface tension isn’t needed. But it looks similar.
I meant to get in the lab this morning and fabricate some devices, but I am not feeling motivated. I ramble a bit about that in the video today. I’m very worried about science funding. That’s dumb. Can’t do anything about it. It’s worrying for nothing. But I am worrying anyway. That’s four hours of my life I will not get back.
Focus on science. Rise above.
