Halloween is just around the corner, and what could be cooler than making your own monster slime? This slime is not only super fun but also a real science project. You'll learn how a few simple ingredients can create something that is sometimes solid and sometimes liquid. Whether you're celebrating Halloween or just in the mood for a cool experiment, monster slime is always a great idea. So grab your ingredients and let's get started!

What you'll need

2 cups cornstarch
1 cup water
green food coloring
googly eyes
spoon for stirring

How it works

First, pour the two cups of cornstarch into the bowl. It feels like very fine powder, right? Cornstarch is the main ingredient for your slime. But what happens when you add water? You'll see, it gets exciting!
Now color your water green or use your favorite color. Slowly pour the cup of water into the cornstarch. It already looks a bit slimy, doesn't it? But you're not done yet. Now comes the crazy part!
Mix it all together with your hands. You'll notice it gets slimy. But now pay attention! If you press hard on the slime, it feels solid. But if you move your hands slowly, the slime suddenly becomes liquid and runs through your fingers. Why is that?
Your slime isn't just any slime. It's called Oobleck. This is a special slime that reacts differently than normal liquids. Oobleck is a "non-Newtonian fluid." If you move it quickly, it becomes solid. If you let it flow slowly, it becomes soft and liquid.
Finally, add the googly eyes. Now your slime looks like a little monster with wobbly eyes that moves and changes between solid and liquid. Creepy and funny at the same time!
So, how does that feel? You've made something really special from just a few ingredients. This is not only a hit for Halloween but is fun all year round! Maybe you want to make more slime in different colors? Who knows what other monsters you might bring to life.
