The first step to the penny lab is to to make sure you have all of your materiel's paper towel,penny,glass of water, eye dropper. Then you lay the penny on the paper towel. After fill the eye dropper with water then drop it on the penny till the water spills over. My prediction for the penny lab was i would get ten drops of water. The outcome though was i got up to 25 drops. I think the reason is adhesion. Adhesion makes water stick together so the water stuck together on the penny until it build up and spilled over.
