At its core, it's a chair test (without the chairs). The participants are seemingly in control of a number of decisions (which are free choices), then they mix with the audience involved (again, it's all pretty free) only to find themselves under the control of the performer by way of a prediction. It's a clean effect. It includes a lot of little touches to make a solid piece of entertainment.

The choices are free, this makes a change from a number of chair tests of recent times... this is very welcome here! (oh and everyone opens their own envelopes) - another big plus, it's a chair test that is about more than just picking a chair.
