TINY HUMAN for scale.

Real science. Ridiculous scale.

A tiny human vs. the biggest, deepest, hottest things in the universe.

Tiny Human is a little astronaut with a big problem: everything is enormous. Each short video drops them into something unimaginable, like the Earth's core or the bottom of the ocean, and shows you exactly what would happen.

You made it to the centre of the Earth. That's 6,371 km down and about 5,400 °C, roughly as hot as the surface of the Sun. Tiny Human is going to need a much better suit.
