Which fizz lever wins this race?
Warm water and extra tablet surface can both speed fizz. What happens when the two levers compete? Build a small model, then race them.
Fizz begins where water can touch
The reaction happens where water meets tablet material. More useful contacts each moment mean a faster modeled fizz.
Warmer water moves more
Keep one whole tablet. In this simplified model, cool, mild, and warm water get 1, 2, and 3 movement units.
Smaller pieces expose more surface
Keep the same total tablet mass. Whole, halves, and fine pieces get 1, 2, and 4 surface units in this model.
Multiply the two factors
Model contact score = movement units × surface units. Try unrelated practice pairs before the real race.
Two levers compete
Both glasses start with equal water and equal tablet mass. Multiply each pair of model units; no product is shown yet.

?1 movement × 4 surface
?Commit before the new setup runs.
Which tablet finishes fizzing first in THIS setup?
Run both contact scores from equal starting mass.
