Julie attempts to use a time delay fuse
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Julie takes the toaster out into the garden, and suspends a slice of bread over one of its slots with string, from a tree. She then places a couple of sparklers along the top of the bread so that, once lit, they will burn the string, releasing the bread into the toaster below. Lighting one of the sparklers, she then runs as far away from it as she can, while Mark keeps an eye on it. Unfortunately, the bread is not released smoothly when the string burns, and simply falls backwards to lie across the top of the toaster, rather than into the slot. Julie therefore fails the task, and earns zero points.
