These elementary science experiments, Penny Drops, challenges kids of all ages. The challenge is to see how many small drops of water will fit on the head of a penny without overflowing.
Even more elementary science experiments.
The reason the water mounded up on the penny was because water molecules are attracted to each other. Each water molecule has a positive and negative charge just like a magnet. The positive side of a water molecule is attracted to the negative side of another water molecule.
The attraction creates surface tension on the water. This is why raindrops form little spheres of water before they begin falling through the clouds toward the Earth's surface.
