One common piece of advice is to chew your food an estimated 32 times before swallowing. It takes fewer chews to break down soft and water-filled food. The goal of chewing is to break down your food so it loses texture. Using a stopwatch on your phone, put all 5 skittles in one persons mouth, find the amount of time it takes to chew the skittles 32 times, swallow the skittles and record the time in the following problem. Take a picture of the stopwatch in the space below.

Record your time in seconds, from #4 below.

From your time in seconds, how many significant figures in the number?
