Russian bar
The Russian bar (or Russian barre) is a circus act which combines the gymnastic skills of the balance beam, the rebound tempo skills of trampoline, and the swing handstand skills of the uneven bars and the parallel bars. The bar itself is a flexible vaulting pole around 4 to 4.5 metres (13 to 15 ft) long, typically made of fiberglass; three vaulting poles may also be fastened together to create a flexible beam.
