Free random facts that are actually true

FactBlast is a free random fact generator with 36 interesting facts across science, history and animals. Tap a category and get an instant fact — the kind of thing that's useless in daily life right up until the moment it wins you a pub quiz or ends an argument.

Every fact here is checked against well-established sources rather than copied from a list of things everyone repeats online. Several of them exist specifically to correct a myth: glass is not a slow-moving liquid, and Napoleon was not unusually short for his time.

Use it to learn something in ten seconds, to have an opening line ready for a quiet conversation, or to feed a group chat something more interesting than a screenshot. The categories keep it useful — animal facts for kids, history facts for arguments, science facts for making someone say “wait, really?”

Facts that make people say “no way”

The best ones compare two things nobody thinks to compare — like Oxford University being older than the Aztec Empire, which is true and sounds impossible.

Facts for kids

The animal category is the most reliable with younger audiences: cube-shaped wombat droppings and three-hearted octopuses need no context to land.

Using facts in conversation

One fact, delivered once, is charming. Three in a row is a lecture. Pick the one that connects to what's already being discussed.
