Color Rain

Coloured rain falls where you press. Steer yellow into blue — green appears.

What your kid practises: Two causes together making a third new thing

We’re building this one right now

Why we made it

Pour yellow rain into blue rain and green appears — a colour that can’t be poured, only made, with a note nobody has heard yet.

Naming colours can wait. What a two-year-old can genuinely discover is that two causes together make something neither makes alone.

Nothing ever gets erased. The paint drifts away on its own, like rain, so nothing your child makes can be destroyed.

1Press keys on different rows — one row rains red, another yellow, another blue.
2Use the arrow keys to blow one colour’s rain into another, and listen for the new note.
3Say what you see: “Look, it went green! More blue. Blow it that way.”

The toy runs in a browser tab, so a curious kid can still find these:

Ctrl+Alt+Del — Windows always lets that through.
The browser’s tabs and address bar (unless you use the kiosk launcher from GitHub).
Swiping in from the screen edge on touchscreens.
