this is a fun way to introduce chemistry students to the subject of pH.

Step 1: Setting Up

each student sets up a square field of centrifuge tubes.
I would recommend a 5x5 field because filling 25 tubes is a reasonable task.

Step 2: Filling the Tubes

in a 5x5 field you would like to create 4 ships
1x fishing boat 1 tube 
2x patrol boat 2 tubes 
1x cruiser 3 tubes 
fill these with a liquid with a pH higher than 8 ( soapy water) 

that leaves 17 tubes which can be filled with highly diluted vinegar.   

Step 3: Ammo

use Litmus as ammunition.
this will cause a correct guess to turn blue and an incorrect one red.

Step 4: Let the Game Begin

let the students play against each other!
<p>sorry but I didn't understood the game can someone please explain it???</p>
What a fantastic idea! I am going to share this with our science teacher!
Great idea.
Oh, I am *so* going to steal this idea! <br> <br>
(Although I think I'll use spotting tiles as the playing boards)
yeah that would also be a nice! <br> <br>but this way you can make them practice with an pipet as well <br>
True, but I was thinking of doing it with pupils aged 12-13, when they are first learning about acid vs alkali.
