One question per episode · roughly 8 minutes each
How does the internet cross the ocean?
Watt & Why answers one big question per episode, fully animated, in about eight minutes. Clear enough for a curious twelve-year-old, sharp enough for adults. Every fact checked against at least two sources, and when scientists still disagree, we tell you that too.

How the show works
One question. Answered properly.
One question per episode
No listicles, no top tens. Each episode picks a single question and stays with it until the answer actually makes sense.
Checked twice, at least
Every fact is verified against two or more independent sources. Where the science is still unsettled, the episode says so out loud.
Animated, not narrated over stock footage
The animation exists to carry the explanation. If a diagram makes it clearer, you get the diagram.
Read instead of watch
Written answers
Some questions are easier to search than to watch. These are the full written versions, with the sources listed.
