Gravitational acceleration + optical illusions + how to! In this Get Set… Demonstrate, science teacher Alom Shaha shows step by step how to create Pearls of Water, a physics-defying demonstration that must look even more unbelievable in person than it does on video.

And if you want to see this in person, the instructions, equipment list, and safety notes for setting it up are here (pdf).

This papercraft pop-up book illustrates how South America and Africa used to be connected, how the supercontinent Pangaea broke apart 200 million years ago, how the Earth's seven primary tectonic plates are ever-shifting, and much more in this TED-Ed by educator Michael Molina: The Pangaea Pop-up.

There’s more paper-inspired science storytelling in the archives, including The Animated Life of A.R. Wallace, stop-motion shorts by Studio Nos, Whale Fall (After Life of a Whale), and another pop-up book: Revolution ( Life Cycle of a Drop of Water).

An animal that can push with 40x their bodyweight, the hairy-tailed mole for example, is definitely something to better understand, and scientists at the University of Massachusetts and Brown University are trying to do just that. So how exactly do moles move so much dirt around as they tunnel underground?
