This smooth runway might look like a freshly-laid tarmac road surface - but it's actually the world's longest trampoline.
Architects in Russia installed the rubber runway as part of an art exhibition - and at 170m long its the biggest ever made.
Visitors have since been bouncing from one end of the trampoline to the other, which is the same length as 13 double decker buses.
The huge trampoline is the star attraction at the Archstoyanie 2012 festival, and has been a hit since it was installed last month.
The space of the festival, as a creative laboratory, builds a territory of experiments in different spheres of art, but foremost in architecture.
The Park provides a rare opportunity for Russian and foreign architects to act like artists by allowing them to create on the "Archstoyanie" ground.
Festival curator Anton Kochurkin said: "The festival got a new quality level and is ready to outgrow the annual format.
"On the territory of "Archstoyanie" there remain objects in accordance to the spatial idea of the Park.
"Of course, art has no practical value but the task that we are working on is to extend the chain where the peace of art becomes irreplaceable, connected with the processes which take place on the area."
