This is a Delmag jumping jack. It was an old school method of compaction . How it works is that when the throttle is engaged, the diesel engine fires and unleashes a violent mechanical or explosive force that compresses and then releases the springs, launching the entire 60 to 100-kg machine into the air.

Poor Family man was sitting on street showing water magic?😱
