Narrative:

I was demonstrating a short field landing in a C150 tail wheel. The landing seemed normal; but we landed on the tail wheel first. After touchdown; I was unable to keep the aircraft rolling straight and it did a ground loop. Upon exiting the aircraft; we discovered the leaf springs to the tail wheel appeared twisted. We were able to taxi the aircraft to the FBO without much trouble. There was no damage other than the tail wheel of the aircraft.
