Me and my class did a very fun, but challenging activity. Each table of 5 students made a cup pyramid. First, we all had a stack of five cups. We also had 5 rubber bands tied to a rubber band in the middle. We all had to pull on the rubber bands on the sides to get a cup. We all pulled the rubber bands to stretch out the rubber band in the middle around and onto the cup. Then, we let go to tighten it. We all then carefully lifted the rubber band and the cup. Then, we put each cup in place. When we were finished there were three cups on the bottom, 2 in the middle, and one on the top. That is how you make a cup pyramid!
