The sky's the limit. Build a tower as high as you can using only cups.

Materials Needed

  • cups
  • the ability to build a tower with them



  1. Build it! How high did you get your cup tower to go?
  2. Why do you think it went as high as it did?
  3. Did you remember to empty the cups first?

We noticed that a curved pyramid base seemed to hold a higher tower. When we stacked cups top to top and bottom to bottom we were able to get the tower higher. With 50 cups we built as high at 34. 5 inches.

I used a package of 400 cups. I did it outside. Eventually. I needed a ladder to reach the top. I kept adding more on the sides and to each level so I could make it taller. When I finally couldn't reach, I found that I had used almost the whole package!
