(If you want to eat your experimental results, make sure you use the blunt ends of the skewers, so you don’t end up poking yourself in the mouth.) For the other half, dip the last 12.7 centimeters (5 inches) of the end of the skewer or string into a cup of clean water, then roll it in a small pile of sugar.

All you need is a lot of sugar, some water and a little patience. If you want any rock candy to eat, anyway. It turns out that that sugar dip is definitely required. Doesn’t that seem like cheating somehow? And is it really necessary? I did an experiment to find out. You’re supposed to dip your candy stick or string in sugar at the start of the process. But the instructions contain a step that seems a bit odd. Making rock candy at home is a tasty way to show chemistry in action. You can repeat the steps here and compare your results - or use this as inspiration to design your own experiment.
