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.
Now this is an effective way for co-curators to remember the names of elements… have the elements explode! Five out of the six Alkali metals react with air and water: Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), and Caesium (Cs).
