Teeterboard

The teeterboard or Korean plank is an acrobatic apparatus that resembles a playground seesaw.

At each end of the board is a square padded area, where a performer stands on an incline before being catapulted into the air.

In the early 1960s the finest teeterboard acts, trained in the Eastern Bloc countries, performed with Ringling Brothers and Barnum & Bailey Circus.

Korean plank acts are featured in the Cirque du Soleil shows Nouvelle Experience, Mystère, Dralion, Corteo, Koozå, Amaluna, and ECHO.

The Hungarian board (bascule hongroise) has a higher fulcrum, and the pushers jump from a height (e.g., from a tower).
