Please enjoy the Nerd-A-Pult. I was very excited when I found it at the Michigan Renaissance Festival last summer. It is a perfect example of Projectile Motion. My family even got involved in showing its marshmallow capabilities during the 1st minute of the video.
Yep, I make physics videos in the hope that you can learn physics. If you are a physics teacher, I am very hopeful that you will want to use them to help flip your physics class.
