NERD test

This is a nerd test that I, being an ukrainian engineer, just figured out. I was integrating a volume and then multiplying by density and gravity to find weight. Anyways, if you figure this out or find this funny, you are a NERD!! (I guess being the creator makes me one!). If you don't know what it is, ask me and I'll explain! (it is not that funny though, so don't get your hopes up.)
