Dr. Roy Lowry of Plymouth University in the UK made science explosively exciting for his class by demonstrating how powerful (and loud) it can be when the pressure of cold, trappedLiquid Nitrogen, a liquified gas, is warmed in a bucket of water. Then he added 1500 Ping Pong Balls.
If that didn’t make sense, watch. He’ll explain it all. And then when you see him pour the balls in and run away (it’s dangerous!), cover your ears or turn down the volume, and let the science commence!
This is a huge mass of ice ”calving" or breaking away from Holgate Glacier at Kenai Fjords in Alaska. We found this video after watching this ice “explosion” that was shot in Wilhelmina Bay, Antarctica. Both are pretty stunning to watch on video, so I can only imagine what it was like to watch in person… as it turns out, watching ice melt can be pretty riveting.
I wasn’t sure that these “daytime fireworks” were compelling (ie. different than any other explosion) until I saw the rainbow around the 50 second mark. Wow.
At the Arab Museum of Modern Art in Doha, Qatar this week, Chinese artist Cai Guo-Qiang put on his largest “explosion event” of the last three years, utilizing microchip-controlled explosives to form incredible designs and patterns. The video we’ve embedded of the event is an impressive testament to how a volatile black powder explosion can be controlled and shaped by computer.
Each set of explosions was calculated to paint a different picture. One series of explosions created black smoke clouds that looked like “drops of ink splattered across the sky.”
