Dry ice is a fun STEM activity anytime but it makes for an especially spooky Halloween 🧙♀️ Did you know that dry ice isn’t actually water? It’s the solid form of carbon dioxide. Instead of transitioning from solid to liquid to gas, it skips the liquid phase. This process is called sublimation. Dry ice can be purchased at most grocery stores but be careful not to touch it with bare skin.
