A kangaroo’s dream come true!!!
In the 1950s, Mr. George Nissen, inventor of the trampoline, jumped on a trampoline with a kangaroo in Central Park, New York.
As a publicity stunt to introduce the trampoline, Nissen hired a kangaroo for a photoshoot in Central Park, New York. The stunt was a success. He started bouncing at one end of the trampoline to get the kangaroo bouncing at the other. Then Nissen timed his jumps so he and the kangaroo would be in mid-air together for the photos.
