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?

Some of your Results

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!
