Dropping/Jolting Floor

[thehauntedhollows]

Does anyone have plans that explain how to build a dropping/jolting floor?

I want to make a floor for next year that drops maybe 1"-2". I will set up an outdoor bridge type structure, basically just raised hallways off the ground. It will have to be extremely sturdy. I have been to haunts where the floor kind of jolts forward and down. How could I make one?



Thanks.

I would use airbags to raise and lower the floor, basically the same way you would build a motion platform, like in the hellevator...

...and quick exhausts are a must if you want it to fall fast.
