Bio help plz

Hi, am at the planning stages of my AS coursework and am doing the pigment test.
I have decided to use an object 30mm long in a test tube and i need to add an amount of water that will cover the object but not too much.
Can anyone help and suggest a suitable amount of water to use?
Thanks!

sorry been at college all day!
i have to do an experiment where i put pieces of vegetable in test tubes. the vegetable pieces are 30mm long and in order to heat them i have to fill the test tubes with water. my teacher said to do it so that is covering the vegetable but not too much, so i was asking for suggestions about how much water to put in the test tubes??

Can't you put enough water to cover the veg? With an extra few ml just to prevent the water from evaporating, and leaving the veg "dry" as it were
