In Space, Fizzing Tablets Dissolve Into Bubbly, Liquid Spheres
Everything is more complicated in space, including heartburn. Astronauts on the International Space Station filmed the process of dissolving an effervescent tablet (like an Alka-Seltzer antacid), showing how the fizzy liquid acts in microgravity.
Instead of mixing neatly in a glass, the tablet fizzes inside the balls of floating liquid, creating a kind of contained storm in a bubble. The super high-definition footage was a test case for NASA's snazzy new RED camera, which is capable of recording in six times more detail than previous cameras on the ISS.
