Two tracks: exhibits still being built and ones that are live. Find the problem, prove it — or help polish what we already shipped.
These aren't ready yet. Find the problem, prove it.
From shiny rocks in rivers to atoms built in particle accelerators — six eras of elemental discovery, quiz-driven and story-rich.
Leave feedback →Fire ants spanning continents. Argentine ants forming trillion-member empires. Explore the strange world of cooperating colonies.
Leave feedback →Real physics simulation of a lunar lander. Thrust, gravity, fuel management. Can you land this thing without becoming a crater?

These are live. Found something that could be better? Or spotted an error?
The uncrewed lunar gateway, the SLS core stage, and the technology making the next moonwalk possible.
The afterglow of the Big Bang — a snapshot of the infant universe from 380,000 years after time began.
How the same material — the same atoms — can arrange themselves into radically different crystal structures.
Every particle has a mirror twin — same mass, opposite charge. Explore what happens when matter meets its mirror.
Four rules, infinite patterns. A cellular automaton that proves complexity can emerge from simplicity.
Earthworms, fungi, bacteria, dung beetles — the unsexy work that keeps every ecosystem alive.
Magnetism, gravity, friction — invisible forces shaping everything, understood through hands-on experiments.
