I am trying to build a set pice for a middle school production of Will Wonka and i need to build the "good nut/egg bad nut/egg" machine with a trap door for the actor to fall through. We want to have the trap door for this but of course safety is one of the most important things in this build. the stage we are using has no trap doors because it is a low unproffesional stage with no way of having anything underneath it and cannot have any kind of damage to the floor. this also needs to be portable. I also do not know how I'm going to build the mechanism to trigger the trap door to open. if we cannot do the trap door then we will just have her duck down behind a elevated platform but if it is at all possible we would like to make a trap door. if you have any suggestions on how we could do this please respond A.S.A.P.
P.S. also keep in mind this is a very low budget production.
