Some couples were given mundane tasks, while others took part in a silly exercise in which they were tied together and asked to crawl on MATS, pushing a foam cylinder with their heads.

The actual disk arms must find the correct cylinder, the control needs to access the correct blocks, and the disk heads have to wait while the blocks rotate to them.

This is made possible by the variable intake system with a throttle valve enlarged from 76 to 82 millimeters, the optimized cylinder heads and an exhaust system with low backpressure.
