WHAT'S PULLING?
For grown-ups
This is a children’s physics door about forces you cannot always see. It is meant to be sat with, not managed. There is no account, no feed, and no score.
How the rooms work
A four-year-old can stop after the first picture and still have a complete visit. Look closer and Keep looking add depth. They are not age labels.
Safety
- Why did it fall?. You can try this. Soft things, a low drop, a clear floor. No climbing.
- It moved without touching. Try this with a grown-up. Use ordinary fridge magnets. Strong rare-earth magnets can pinch skin, wreck phones, and interfere with medical devices. Keep those in a drawer. Magnets are not for mouths.
- The balloon that stuck. You can try this. Balloons and small parts are a choking risk for little siblings. No wall sockets. No plugging anything in. This is not household current.
- Air is pushing. You can try this. Do this over a sink. Plastic cup, not glass. No boiling water, no crushed cans on a stove, no sucking air from a bottle with your mouth in a way that hurts your ears.
- The Moon keeps falling. Watch this one here. A look at the sky and a drawing. No projectiles. No climbing to throw.
- The ocean moves. Watch this one here. Do not walk out on rocks, piers, or mudflats to chase a tide. Open water and incoming tides are not a children's experiment.
Never strong magnets near phones, computers, or medical devices. Never mains electricity. Never storms, open water, or height experiments.
Privacy
No child account. No login. No ads. No location. No public submissions. This page does not ask for a name, birthday, school, or email. Optional listening uses a static recording. This device can remember where Eve paused, only in this browser session. Nothing is sent back about the child.
We do not claim the internet is completely private. This project simply does not collect those things.

- NASA Space Place: What is gravity?. Gravity is a pull between objects. It holds planets in orbit too.
- NASA: What is microgravity?. In a vacuum, gravity causes all objects to fall at the same rate.
- NIST: How do you measure magnetic fields?. What a magnetic field is, and how it is measured.
- NASA: Earth's magnetosphere. Earth itself is a magnet. The same kind of field, scaled up.
- Science World: Static electricity. Electrons move onto the balloon. Same charges push. A nearby neutral thing can be induced to attract.
- ASME: Ways to demonstrate air pressure. Ordinary air pressure is a real push. The inverted cup holds because of that push.
- Buffalo Museum of Science: The power of air. Atmospheric pressure is the weight of air pushing on everything.
- NASA Space Place: What is an orbit?. Always falling toward the planet, moving sideways fast enough to miss.
- NASA: What is microgravity?. About 90 percent of Earth's gravity still reaches the station. Astronauts float because they are in free fall.
- NOAA: Gravity, inertia, and the two bulges. Two bulges, near side and far side. The Sun also plays a role. The Moon is the main pull on the ocean.
- NOAA NESDIS: What causes tides?. Tidal force is a differential force: the pull minus the average pull.
- NASA: Tides. Oceans bulge on the side closest to the Moon and the side farthest away. The Sun joins in.
