snarky y'all are, lol

The broom is very low tech, in the straw section there is a tupe and they just shove a stick up it and wiggle the broom up the trap door and she grabs it. On tour it looks nicer because it 'floats' in from the wings on a wire.
The benches and beds and all other scenery is driven/pulled on by wenches in the stage deck with cables and motors and all that stuff
