Powder Keg (originally named Hannibarrels) was a Calypso / Teacups hybrid built by Swiss manufacturer Intamin that was previously located at Six Flags Over Mid America in Eureka, Missouri, USA.


Hannibarrels opened with the park and operated through the late 1990s. It was renamed Powder Keg in one of its last seasons.

The ride remained standing but not operating for many years after its closure.[1] Demolition began in December 2013 to make way for Tsunami Soaker.[2]
