ISS astronomers placed an effervescent tablet in a floating ball of water and captured it on camera.

International Space Station astronomers recently placed an effervescent tablet in a floating ball of water and captured the outcome on camera.
The visuals were filmed using a Red 4K camera which can record at a much higher resolution than typical HD cameras.
NASA says the cameras are undergoing an evaluation for gathering science data in a wide variety of settings.
Uploaded on Monday, the footage showing the tablet dissolving inside the weightless water bubble went viral right away.
