Penny water holder

Filling up this penny with water up to the bronze brim was surprisingly easy. After remembering what I had learned previously, I realized that cohesion and adhesion were responsible for this cool bubble of water sitting on the face of Abe. Adhesion is a property when water molecules stick to an other object. The molecules stuck to the penny, which then allowed cohesion to happen. Cohesion is a property when molecules attract to each other or "stick together." The molecules are holding each others little molecule hands to stay in a bubble like stack on top of the penny. Although this interlock is pretty cool, it isn't very strong, and can be broken and spill just by adding a little too much water to the brim of the penny. Also, if any non polar substance touched the water, the bubble would collapse as well. This is because water is polar. 

     Carefully putting more water onto the penny, too much and it could all be over!
