Reinhard Lorenz has been in the bouncy castle rental business for 15 years. The 59-year-old has rented a large hall on a farm due to lack of space.

In between are two large plastic cows, which are often borrowed for milking competitions, as well as two bull riding facilities, a children's railway and various other entertainment equipment. The prices for a castle range from 1000 euros for a cheap product from the Far East to 4000 euro for a "Mercedes"
