Great video! This references the fantastic book Flatland, which helps explain dimensionality in really easy to understand way, and helped me get my head around what a 4th or n level dimension is (and why we it’s so unintuitive for us 3-dimensional beings)

Is that book okay for a 10yo girl?

		yes? it's got sexist and classist elements and satirizes victorian culture. i'd encourage reading it ahead of gifting (and i'd encourage grabbing it from archive.org or something, since it's 141 years old) because not all 10 yearolds are going to receive it the same way
