Overview

We love finding sustainable, cheap ways to make teaching tools. This guide will walk you through how to make a wind tunnel, so your students, regardless of grade level, can explore physics in a hands-on way!

The hardest material to source is the plastic sheeting. We used a material called PET-G, a type of plastic with a low melting point that's most commonly used for making hollow shapes like clamshell packaging. We're lucky to have many plastic supply companies located around Norristown, so it didn’t take long to find a local business that could sell us a single 4' by 8' sheet of PET-G. Since PET-G is pretty sturdy and retains its shape well, you need a pretty thin sheet, 0.01-0.05” thick. You could probably follow this guide and use vinyl sheeting instead, but it will probably need to be thicker in order to retain its shape.
