If you’re looking to “spook-a-fy” your Halloween decorations this year, the Museum of Science and Industry (MOSI) has a fun idea — Dry Ice Bubbles.
MOSI educator CJ Kreisler explains the science behind the trick: dry ice is frozen carbon dioxide that skips the liquid phase, going straight from solid to gas in a process called sublimation. At around -100°F, it produces a visible fog when placed in water. Add a dash of dish soap, and the reaction creates smoky, bubbling spheres that are perfect for haunted houses and spooky displays.
MOSI will feature the Dry Ice Bubbles experiment at its family-friendly Spooktacular Science event on October 18, alongside carnival games, a scavenger hunt, DIY popcorn slime, liquid nitrogen ice cream, and more.
