The taste buds let the tastes of bitterness, saltiness, and sourness. Test subjects held the breath while having different liquids in the mouth. This was done with Water, salt water, sprite, sunny d, milk, and lemon juice. Milk seemed to affect the time the breath can be held the most. This result was not expected because milk has such little acid level, so lemon juice was expected to affect the time the most.
