Introduction  

Did you know that you can engineer almost anything with just some basic materials? Engineers in the real world create prototypes, working models, out of cardboard all the time. 

​

For this design challenge, look around for some cardboard- any kind will do! Boxes, recycled packages, paper tubes, whatever you have on hand. Then see what you can prototype! Try building a tall tower or something strong enough to hold weight. Test out your prototype and see how it performs. Make changes and keep experimenting!
