Eva creates an ineffective needle-finding tool

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Eva immediately declares that a magnet is needed, and leaves the lab to find one. She returns with a wooden pole, a magnet and some duct tape, and uses them to assemble a tool that she can thrust into the haystack to collect the needle. Apparently not having any joy with her tool, she ends up on the floor, rummaging around with her hands. She eventually finds the thread, and is able to follow it to the needle. She completes the task after 28 minutes, and earns fourth place.
