Space Lab is a science game about predicting what really happens — not
memorising facts. Pick a world, make your call, then watch the physics play
it out.
THE SEVEN EXPERIMENTS
🪐 Float: Planets — Which worlds float, and in what?
🌙 Float: Moons — Same tank, icier samples.
🧪 Layered Column — Ten liquids stacked. Where does it come to rest?
🦘 Jump Lab — Could you jump off it and never come back?
🔄 Spin Lab — Its day against its year. Which finishes first?
💥 Ring Lab — Pull a moon closer until tides tear it into a ring.
❄️ Phase Lab — Freeze, boil, or stay liquid?
REAL NUMBERS, NOT MADE-UP ONES
Every figure comes from published planetary data: densities, escape
velocities, rotation and orbital periods, surface temperatures and pressures.
The surprises are real ones.
• Deimos needs 5.6 m/s to escape. A strong human jump reaches about 4.5.
A running leap is the difference between staying and leaving forever.
• A day on Venus lasts longer than its year.
• Phobos already orbits inside its own break-up limit. Mars is going to
have a ring.
• Water is rock-hard ice on Titan — while methane falls as rain and pools
into lakes.
WHAT'S INSIDE

FOR CURIOUS PEOPLE OF ANY AGE
Built for classrooms, long car journeys, and anyone who enjoys being wrong
about something and then finding out why. Every answer comes with the
explanation.
