Facts worth wondering about.

Real science. Impossible journeys. True stories that sound made up.

4 km down. Deeper than the deepest mine on Earth.

Every video drops you into a journey no human could take.

Factavity turns real science into adventures for curious minds of every age. You dig, dive, fall and climb, and on the way you find out how the world really works.

You are the explorer

Each story asks "what if YOU…?" and then takes you there, step by step, so the science is something you see happen.

Every fact is checked

Numbers come from real research: mines, boreholes, space agencies, museums. If we can't source it, it doesn't go on screen.

Turns out…

Every journey ends on the twist that made us want to tell it. The real world is stranger than anything made up.

12 km down. Humans stopped here. You don't.

2,890 km down. The rock gives way to liquid metal. Journey 01

What if YOU dug straight down from KL?

You grab a spade in a garden in Kuala Lumpur and start digging. Past the deepest mine, past the deepest hole ever drilled, through the mantle and the liquid-metal core… and out the other side.
