Suggested Play (For 2 to 4 players)
1. Spread the water beads on the table or tray.
2. Player 1 shouts out a colour and starts the countdown timer at 1 minute. Player 2 (or the rest of the players if more than 2 are playing) has to pick up as many water beads in that colour with the tweezer (or spoon for younger children) as possible and place them in a cup before the 1 minute runs out.
3. Take turns to pick and call out the colour.
4. Count the number of water beads in the cups. The player with the most water beads wins!
