Water Challenge Bingo

A friendlier way to drink more water: tick off habits instead of counting ounces.

How to use it

Tap “Print 6 different cards” to give everyone their own shuffled card — the squares are the same, the order is not, so there is a real race to five in a row.

Set a time limit (a weekend, a week) and a small prize. Prizes that are time together tend to beat prizes that cost money.
