A shiny orb! A floating shiny orb! Water bubbles that pop out of the floating shiny orb! This is the magic that would happen when you pop an effervescent tablet (Alka-Seltzer!) into a water bubble in space. It’s cool to see the little bubbles form within the blob of water and then see things start flying off the orb like little water spaceships flying out of a mothership.

Astronauts on the International Space Station dissolved an effervescent tablet in a floating ball of water, and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station. This footage is one of the first of its kind. The cameras are being evaluated for capturing science data and vehicle operations by engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
