auromontanomoriphobia
Morbid fear of Rube Goldberg devices, elaborate systems built from everyday objects to convey mechanical energy across a given distance.
The candle burns the string which releases the hammer to knock the golf ball down the chute where it sends the row of nails rolling on their heads into each other and then ... oh NOOOOOOOO!!!!! I've got auromontanomoriphobia, get me out of here!
