A browser physics toy

Drop it,
and let it
bounce.

Every tag on this page has real mass, spin, and a stubborn habit of falling. Grab one and fling it. Click the floor to pour more. It isn't a video — it's a little rigid-body engine, tumbling live under your cursor.

/ the physics

Three rules,
one honest pile.

No easing curves faking it, no pre-baked animation. The pile you build is solved fresh every frame from three numbers we happen to like.

01

Gravity

There is only one direction that matters, and it is down. Every frame each chip gets a touch heavier with speed until the floor says otherwise.

02

Restitution

Bounce is a budget. We spend just enough for a satisfying hop, then let friction quietly pocket the change on the way down.

03

Friction & spin

Contacts aren't just stops — they're nudges. Every graze adds a little torque, so no two chips ever settle at quite the same angle.

/ the jar, live

Watching the
numbers fall.

These aren't decorations. They're read straight off the running simulation at the top of the page — scroll back up, pour a few, and watch them climb.

Make a
glorious mess.

We built the engine. The pile is entirely on you. Pour a hundred chips at once and see how high TUMBLE really stacks.
