Chris swaps buckets
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Chris started with a bucket containing 2 ducks, then swapped his bucket with Josh's to have the bucket with 5 ducks, before Paul swapped his bucket with Chris's so he then had 1 duck. As Chris ended up with 1 duck in his bucket, he received 1 point.
