If anyone is interested in collaborating with Physics Girl on Youtube, feel free to contact her directly (email below). She is currently open to suggestions, but is also looking for helping researching physics concepts, having people be in here videos, in addition to script writing. This is a fun way to learn about physics outside your classes so I definitely suggest emailing her!
