If I worked for Edexcel, I'd give Caroline Flack an A* for her physics experiment.

Listen up, buttercup. This "joke" is dark. Caroline Flack was a TV presenter who committed suicide. The "physics experiment" is a twisted reference to her death, implying she "experimented" with gravity. So, the joke is about suicide. If you find it funny, then you are as smart as the guy who came up with it.
