I don't think this is a good test because these questions allow you to trade off knowledge for creativity, and LLMs have vast internet knowledge. It's easy to find listicles with creative uses for all of the objects in the test.

Now, this applies to human creativity too! If you ask me for an alternative use for a pair of jeans, I might say that you could cut them up and braid them into a rug. This isn't my creative idea; I just happen to know there's a hobbyist community that does that.

I think in order to test creativity you need constraints. It's not enough to find uses for jeans, you need to find uses for jeans that solve a specific problem.
