Happy Halloween! Our lab technicians are back with another spine-tingling science experiment, and this one’s guaranteed to cause a stir (and a little fog) in your classroom.
Using hydrogen peroxide and a dash of manganese (IV) oxide, this classic demonstration rapidly decomposes the solution to release heat, oxygen gas, and steam, creating a dramatic Halloween Fog Effect! It’s a brilliant way to capture attention and spark curiosity about chemical reactions, decomposition, and energy changes… all with just the right amount of Halloween magic.
This demonstration is a fantastic example of how chemistry can be brought to life in an exciting way.
🎥 Watch the video below to see the experiment in action and bring a little Halloween spirit to your next science lesson!
