I have to teach some basic thing to a class of twenty three girls this week and I'm drawing a blank on what to do. The other students in the class have done simple things like making stress balls, paper cranes, and making slime. I would like to do something small like that that wouldn't take more than thirty minutes to do. Also, I have three 100 foot bundles of rope that I am able to use if needed.
So, what can I teach them?
