Showing a button to a scared little kid, convincing them to actually push the button(on a remote control) then something happens in the next room, all controlled by that small hand-held single button.
I see the "lights" go on in their head as a new realization dawns there, "They can have some of this fun too!"
The next button they push scares their family members but not them.
This is a very popular experience for the child. I just made a future haunter!
Or at the very least a future haunt customer.
Most of these formerly scared little kids then remain in the tour......this is how you "grow" your spooky business.
It feels great to me!
