In this new video from NASA, astronauts aboard the International Space Station play with a ball of water by adding Alka-Seltzer. Oh, it bubbles, alright, but those bubbles really don’t have anywhere to go, so they just float around inside the orb. One occasionally explodes from the surface, but there’s not enough gravity to force it upward, because there really is no “upward.”
NASA is excited about their new Red Dragon camera, which captures images in 4K resolution. You can read more about it at their website. It will enable scientists on the ground to observe experiments on the ISS as well as the crew does. If you want, you can change the YouTube resolution to the highest level under the settings button, and see each bubble clearly.
