Have you ever heard your students ask: “How do planets form?” “What makes some orbits circular and others elliptical?” “Why don’t planets fall into the Sun?” “What causes tides—and why do objects sometimes get pulled apart?”
Arbor Scientific’s Gravity Well turns those abstract gravitational ideas into a vivid, hands-on experience. Built for teachers who want reliable demos and real discussion starters, it makes orbits, tides, and system formation easy to see and easier to teach.
It’s a classroom model of curved spacetime: a collapsible frame with a stretch fabric “well” where marbles act like planets and a heavier ball stands in for a star. Students can watch material coalesce, compare orbital periods at different radii, and explore escape paths—using simple, repeatable setups.
Orbits & Kepler’s Laws
See circular, elliptical, and escape trajectories; compare orbital period vs. radius.
Tidal Forces
Roll a cluster of marbles and watch it stretch and separate—your live Roche-limit demo.
System Formation
From chaos to order: collisions, coalescence, ejections, and a shared direction of orbit.
Force & Motion Connections
Discuss why speed changes near periapsis and how inward force sustains an orbit.
And much more!
Make gravity visible and memorable. The Gravity Well delivers repeatable results, whole-class engagement, and big “aha!” moments in your physics lessons.
✅ Built for physics educators
✅ Backed by teacher feedback
✅ Supports real-world, standards-aligned learning
Give your students a reason to remember physics—weave engagement into the fabric of space-time with the Gravity Well and start running orbit labs tomorrow.
