 * TESTING THE STICKINESS OF DIFFERENT CANDY**

The purpose of this experiment was to find out how sticky crushed and whole candy is. The hypothesis was that crushed candy would be stickier, because it has more surface area to get sticky than whole candy, and the lollipop would be the stickiest candy. First, two packets of sugar were poured into a beaker and the mass was measured. An area about 15 mm in diameter on the whole candy was licked ten times, delivering about 0.5 mL of spit. The candy was dipped into the sugar, and after some rolling around, extracted. The difference in mass was measured and the experiment was repeated. Next, the crushed candy was tested. It was crushed up with a mortar and pestle. 0.5 mL of water was added with a dropper. Then, about 1.5 grams of the mixture was dumped into the sugar and tossed around, then extracted. The difference in mass was noted and the experiment was again repeated with some of the candy used in the past experiment. The results showed that the candy increased in stickiness by almost four times than when whole, proving the first hypothesis correct, and the lollipop wasn’t the stickiest, proving the second one wrong.
 * ABSTRACT**

Some ways this experiment could be improved are that the exact mass of the candy being dunked in sugar, the number of tosses of the candy for the second experiment, and the number of swirls for the first experiment would be measured. Some future experiments could be testing different candy, and testing thingsthat aren’t candy at all like grape and apple juice, and comparing them to the candy and to each other. Also, other features of the candy could be studied, because those could cause the candy to be sticky as well. For example, the sourness of the candy could have something to do with the stickiness. The gelatin in the gummies could cause them to be stickier than the mints.
