# Will the wall I've built withstand strong winds?

In this lesson, we will be investigating which materials can be blown down by creating our own wind using a hairdryer. We will be experimenting with different types of materials which have different weights. We will be using our structures from the previous lesson, 'Which materials can withstand strong winds?' to experiment with. If you do not have these things, you can watch me model this experiment.
