    What you are changing: We are changing the steps. Instead of dropping the paper towel in the water and vinegar, we are mixing the water and the baking soda together then adding the vinegar to the mixture.

    What are you measuring: We are measuring the reaction time.

    Hypothesis: We think the reaction will happen faster because we are not using the paper towel to slow it down, and also how much the bag expands.

    Results:1st time: 0.33 sec
    2nd time: 0.48sec
