Spooky Science: Halloween Experiments to Get Kids Excited About STEM!

At Carus, we’re passionate about inspiring the next generation of scientists. What better way to do that than with fun, Halloween-themed experiments that combine the magic of chemistry with the spirit of the season?

Our spooky science experiments—like the Witch’s Brew, Monster Slime, and the Mad Scientist’s Lava Lamp—are designed to show the fascinating principles behind chemical reactions, density, and non-Newtonian fluids. Not only are these activities a blast to watch, but they also provide a hands-on way for kids to learn about states of matter and how different substances interact under certain conditions.

Experiment Highlights:

Witch’s Brew: Watch in amazement as hydrogen peroxide, yeast, and dish soap create a foaming, bubbling reaction that pours out from a witch’s cauldron.

Monster Slime Concoction: Create your very own spooky slime using household ingredients, while learning about the unique properties of non-Newtonian fluids—substances that behave like both a solid and a liquid.

Mad Scientist’s Lava Lamp: Dive into the science of density and watch as oil, water, and Alka Seltzer form a bubbling, lava lamp-style reaction.

Whether you’re a parent, teacher, or simply curious about science, these experiments bring the wonder of chemistry to life. We hope you’ll join us in sparking curiosity and excitement about STEM while having some Halloween fun!
