Tobias catapults a shoe into a bathtub
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Tobias reads the task a few times, and realises that while the catapult must be built on the red mat, the task does not forbid subsequently moving the catapult. Tobias builds his catapult out of a golf club bag (presumably because it has wheels, so is easily moved) and a butterfly net, and launches his shoe directly next to the tub. After a few tries with the butterfly net, he swaps it out for a short shovel, and successfully launches the shoe into the tub. Tobias finishes in 4 minutes 12 seconds and wins the task.
