I went to an improv class last night

It is genuinely one of the most fun experiences I've had. There were 11 of us. There are no physical props; all props are imaginary. So our instructor, C, says "I have a red ball" and pantomimes, and then she throws it to someone, who catches it. And we go around the circle, saying "Reed, here's the red ball; M, here's the red ball" throwing it to one another. C grew the red ball & shrank the red ball and eventually I ate it and then conjured a blue ball. C then shifted us to ... you smash (or whatever) the object and turn it into a new object and throw it to the next person. A paper airplane, a flower, a Dove was turned into a fly, etc etc. Then we did a game "Zip, zap, zop" which was surprisingly more fun than it sounded. One person says "zip" and makes a hand motion toward another person in the circle (like a clap but one hand goes forward, the other comes inward). The target then "zaps" to another, who then "zops" to the next, and we go around zip/zap/zopping eachother. It's funny…
