What is the experimental control and variable in this experiment?

Three different brands of tissues of same size were dropped in 5ml of water. I do not understand what's the experimental control and experimental variable. Is the experimental control and control group the same thing?|||The variable is the thing you change, in this case the brand of the tissue.


The control is the thing that stays the same, i.e. the size of the tissue and the amount of water.
