// A foil boat that carries the most coins
⏱ about 20 min

Friday: Test Boat Version 2

Raven folds a wide, flat boat with low walls.

It looks like a tray.

Rocket adds coins, spreading them out.

Nova keeps count. "Twenty, twenty one, twenty two..."

At last, water trickles in. "Twenty two coins!" Rocket shouts.

Compare honestly

The wide boat carried many more coins.

The foil, the water and the coins stayed the same.

Only the shape changed.

Your numbers may be different, and that is okay!
