In this experiment, you’ll explore how particles move and interact. You’ll drop different particles into water to see which ones come together and which ones stay apart.

What you’ll learn

There are invisible forces that control how particles move and interact in the Universe.

Large bowl
Water
Glitter, confetti or small pieces of paper

What do you think will happen when you sprinkle the glitter or confetti into the water? Will the pieces come together, stay apart, or move in random directions?

Fill ¾ of the bowl with water.
Pick up a small handful of glitter or confetti.
Slowly sprinkle it into the bowl.
Observe what happens.

Were the pieces attracted to each other, or did they repel each other? Or neither? Or both?
How did the pieces move in the water with no outside force (touching, blowing)?
How does this experiment relate to the story of how the Universe came to be?
