Season 4's Double Barrel
The Double Barrel is an obstacle, first introduced as the fifth and final obstacle in the Qualifier of Season 4’s Summer Wipeout. It was interchanged with the Wipeout Kitchen from Spring as the second post-Big Balls obstacle for the rest of the season.
It is a large spinning pill-shaped board with two circles, making it look like the front of a double-barrel shotgun. Placed on either side of the structure is a narrow walkway. Contestants must hop into one of the circles, ride it around for a bit, and finally dismount the circle onto the finish platform.
