Matthew is our Scientist of the Week! He demonstrated an experiment called Sticky Penny.
In this experiment, we used a penny, an eyedropper and some water to show how water collects on the surface of the coin. We predicted how many drops of water we could put onto the penny without the water overflowing.
Most of us predicted 5-10 drops. But we reached 21 drops before the water overflowed! We learned about molecules, cohesion and surface tension.
Way to go, Matthew!
