Mock disaster in Maine

This saturday there is going to me a mock disaster, i just signed up and now i just need to wait till Saturday. whats going to happen is there going to pretend a big boat ran into the dock and crashed and sunk during a sailing lesson. what im going to do is still a little bit unclear, but i do know that i will be made up with make up and stuff to look like i had serious injuries, and also they are going to take some people to hospital in ambulances, and they are going to land a helicopter on the town green. (this is all very exciting for this town because its so small, about 300 people live here year round. and only 4 business)
