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?”
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.
