The act fits inside my suit, so that I can just walk around and perform for people. This helps everyone mingle and gives people things to talk about. It also makes sure I can contribute to the flow of an event without interfering with anything else happening.
I also have a full stage show. It is entertaining, fun, and magical — it's also very family friendly, and will be talked about later. I normally mix the two — a walk-around set of magic followed by a ten minute show makes for a great evening!
