The straw jet is a great activity for learning about airfoils. Using a straw in a classroom during covid times is not a good idea though. This is a set of attachments for soda or pop bottles that allows you to safely launch straw jets in a classroom.
There are a variety of designs. I really do not have a favorite yet. I was trying to find one that printed most clean, but in the end they all worked about the same.
