Surprising Everyday Facts
Did you know that some of the most ordinary objects and phenomena have an extraordinary story or a hidden scientific secret? It’s true!

Weird but True World Records
World records capture kids’ imaginations because they represent the extreme limits of human and natural possibility.
- Longest Pizza: In 2017, a team in California made a pizza that was over 1.3 miles long. That’s enough pizza for everyone in your town and more!
