STEAM Challenge 05 – #FluxSTEAM5

Tower Challenge

Testing your building and engineering skills!

For this challenge, you will construct a tower made of craft and recyclable materials (paper, tape, toothpicks, popsicle sticks, etc.). See below – for Tallest Tower Prize you may not use building toys (Legos, K’NEX, etc.) You can still build with those but you will not be eligible for that prize using those.

Your tower should be able to at least support a tennis ball or object with a similar weight off of the ground. The tower should be free-standing, not supported by anything but itself.


  1. A Tower that can hold a tennis ball off of the ground
  2. A short video (Max. 2 minutes) explaining how you built the tower, materials used and showing the tennis ball or similar object off of the ground with proof of a measurement. See image below.

Research and Brainstorm

What features of a tower are important? Why and how does a tower stand on its own? What brings strength to a tower? Any specific shapes, features, that make it strong.

If trying to for the Tallest Tower supporting a tennis ball, only craft materials can be used, no building toys. Measure from bottom of tennis ball to the ground.


Build Your Tower

The Goal: To support/hold a tennis ball or similar object in weight off of the ground as high as possible.


  • Has to be free-standing, standing on its own.

    • Rolled up paper/newspaper, recyclable materials, tape, popsicle sticks, toothpicks, etc.
    • To be eligible for “Tallest Tower” do not use building toys such as Legos, K’NEX, etc. or lumber (scarp wood, 2x4s, etc.) Towers can be built with these but will not be eligible for the “Tallest Tennis Ball Tower” prize.
