Behold the Beauty of This Bouncing Blob of Liquid Loveliness on the Space Station

Astronauts on the International Space Station have stepped up the entertainment factor of their fluid dynamics antics. They’ve added food colouring to the already-excellent combination of zero gravity, water droplet, and antacid tablet, creating a sparkly disco ball of pure joy.

NASA astronaut Terry Virts captured beautiful footage of an antacid tablet within a floating water droplet with the high-resolution RED Epic Dragon camera over the summer, but now Scott Kelly has an even more lovely update. But the purpose isn’t just to create something beautiful: the astronauts are also testing out the camera’s capacity to capture fine details during experiments. The details of each bubble are highlighted by the bulging droplet, fizzing into a lopsided oblate blooping around the station.

Zero gravity + water droplet + food colouring + antacid tablet = perfection

The only real question is if the space station is getting ready for a retrotastic light show for a raging dance party, or if this is some early prototype that will eventually evolve into Slimer from Ghostbusters.
