Back in the 1970s the traveling carnivals would have a fun house and they would have something like this except the floor in addition to moving forward would move side to side violently and they had Subway style hooks that you had to reach up as far as you could above your head and hold on with both hands and instead of having an automated sensor that activated the air there was a guy standing off to the side hidden that would see when the woman was over the vent and the vent was a good five or six feet long and they had a giant air tank with nozzles that would dump a huge amount of pressure all at once and it would blow the dresses and skirts right up above their heads and even dislodge them pulling them up to their breasts and because the floor was shaking violently side to side they wouldn't let go well most of them wouldn't let go of the hooks and you'd see this large crowd of guys and boys standing around at the end of the fun house watching the show With me too these rides are no longer allowed in the United States and as far as I know they are not allowed in Europe either It's such a shame
