Straw Tower

A skyscraper made of straws

Materials Needed

  • straws
  • scissors
  • straight pins
  • thimbles
  • shoe box
  • 100 pennies



  1. Build a skyscraper that can hold a shoebox filled with 100 pennies.
  2. You can only use straws and pins to build your skyscraper.
  3. Pins can be very sharp, so make sure you get permission to use them, and make sure to use thimbles to help press the pins through.
  4. Good luck!

How would you have to change your skyscrapers if you used something else, like tape, to connect the straws? Try it out, and if you come up with any cool designs, send them to ZOOM!

Well, when I finally went on zoom and saw the straw tower I just had to try it out because, I collect straws when I did it the first time it didn't stay but the next time I did it it stayed up just right.

We built tall sky scrapers in science class, using only 50 straws, 50cm of tape, & 25 paper clips. That is all!!! Our teacher got a ruler & laid it on top of our structure. She tied a piece of yarn on it, & attached the yarn to a bucket, which hung down from our structure. We put 657 grams in the bucket, then it collapsed!!! Our structure held the most grams!!! You try it like that!!!

When I was doing the staw tower it looked kool. When I was done I put some books on it. I put 6 books then it crashed. Then I did it once more. It did not work but that time it had 7 books. The 1st time I tryed this I used very little tape then the 2nd time I put more tape on it. This is why I think it would hold more because the tape was strong the 2nd time. It was stronger the 2nd time and not that strong the first time.

Evelyn, age 6 of San Antonio, TX wrote:
We made a straw tower, but used no tape. It was pretty short, and square-shaped. We could balance books on it and the tower would bounce like jell-o. Sometimes the staws would roll away. The staws were like shock absorbers.

April, age 11 of Fountain Valley, CA wrote:
First it stayed up because it had a lot of support but then we took the support away and it fell.
