A weight with a hole in the middle, such as a large washer. Or you can make a weight by taping pennies to the end of a toilet paper tube.
We challenge you to make a paper tower that can withstand as much wind as possible.
There are 3 constraints for this challenge (an engineering constraint is a limitation on your design):
You only have 4 sheets of paper and tape to build your tower – nothing else.
The tower should be free-standing meaning it can’t be taped to the ground
And, the tower has to be strong enough and tall enough to hold the weight at least 14″ above the ground
Brainstorm Designs and Build
Sketch out a few ideas. Think about how you can build your tower so it’s really stable, but doesn’t catch too much wind.
Set up a fan 6 feet away from your tower. Set the fan on low and see how it does. Did your tower withstand the wind? Try moving the fan forward in 1-foot intervals until your tower blows over. How close can you get?
Evaluate and Redesign
Did your tower do as well as you thought it would?
Did your tower slide rather than blow over, or the other way around? Why?
What could you change to make your tower even stronger against wind?
