My fellow haunters:
This year I would like to build a big red button prop that would electronically actuate a scare.when pressed. I don't want to use pneumatics and I don't want to use a super loud horn. I am trying to think of other ideas that may scare but not harm. I like the idea of an air cannon but the only ones I have seen are pneumatic. I like the idea of super bright spot light coming on coupled with another sensory overload... Thoughts?
Thanks in advance.
