Real physics. Build it, run it, then write it as code.
or jump straight in: Everything you save stays on this computer. Privacy
Each one sets up an experiment and explains what is happening.
So your scenes stay yours on a shared computer.
Your recovery code — the only way back in if you forget your password.
The twelve characters you wrote down when you made the account.
Everything about it lives on this computer.
Lost the one you wrote down? Get a fresh code — the old one stops working straight away.
Your scenes stay saved and come back when you sign in again.
This removes the account and every scene saved in it. It cannot be undone.
The boy who built this.
I am 11 years old, and I built Tumble Studio in 2026.
I love learning, and I love helping other people learn. I hope this helps other kids find out about physics — why things fall, why they swing, why they knock each other over — by building it themselves and watching it happen.
Everything in here is real physics. Nothing is a cartoon.
Small choices, kept on this computer.
The quick tour points out the menu, gravity and the Play button. It opens every time you start building until you tell it not to — and the ? at the top of the studio always brings it back, whatever this says.
You do not need an account at all.
Everything in Tumble Studio works without an account. Your scenes save straight onto this computer, and they will be waiting for you next time you open it.
If you share this computer with a brother or sister, ask a grown-up to make an account so your scenes do not get mixed up.
