This is a video of a mercury-filled balloon being dropped in slow motion. Mercury, as I'm sure you're aware because we're all scientists here, is 13.5x as dense as water and can be poured directly into a balloon with a funnel to fill it up. That alone was pretty neat. But the way it flattens a balloon when dropped is even NEATER. You know, I remember my dad telling me a story from when he was growing up that he and his siblings accidentally broke a thermometer and spent hours and hours pushing around the beads of mercury on the kitchen table. Those were simpler times.
Keep going for the video.
Thanks to Derrick, who is going to try the same thing but with plutonium. Whoa -- watch out for superpowers.
