@MarkRober and @ScienceBob teamed up for one MASSIVE chemical reaction at the Museum of Science! 🐘🧪 During Mark’s event at the Museum, the duo created a spectacular eruption of bright green foam with an Elephant Toothpaste experiment! Here's the science behind it: A catalyst speeds up the breakdown of hydrogen peroxide into water and oxygen gas. Dish soap traps the rapidly released oxygen in thousands of tiny bubbles, creating an enormous burst of colorful foam! #MarkRober #ScienceBob #Experiment #Chemistry #Science 04 Nov 2026 @sciencebob has some spooky science for us, including how to make ghost cannons and puking pumpkins! 🎃 👻 @markrober @crunchlabs 28 Oct 2026 @sciencebob 28 Oct 2026 Knot quite magic. 05 Oct 2026 May the engineering be with you. 07 Sep 2026 Camp is officially in session.
