Does rock candy melt in the sun?

Here's why:

* Sugar's Melting Point: Sugar, the main ingredient in rock candy, has a melting point of around 320°F (160°C). While the sun doesn't reach that temperature, it can still be hot enough to melt sugar, especially on a very sunny day.

* Direct Sunlight: Direct sunlight will heat up the rock candy more quickly, increasing the chances of melting.

* Dark Color: Darker rock candies tend to absorb more heat, making them more susceptible to melting.

However, it's important to note that:

* Rock candy usually has a lower melting point than pure sugar. This is because of the impurities present in the sugar and the moisture content in the rock candy.

* Rock candy will melt more quickly if it is exposed to direct sunlight for a long period of time.

* Rock candy is more likely to melt in hot, humid weather.

So, if you want to keep your rock candy from melting, it's best to store it in a cool, dry place.
