A test is set up to test which brand of soda creates the biggest foam explosion when adding a Mentos candy.  Three different sodas were tested. They measured the height of the foam eruption.   What is a controlled variable (constant) for this experiment?

• Brand of soda
• Number of mentos candies used
• Height of foam eruption
• All are controlled variables (constants)
