As Halloween is right around the corner, here's a video from ByteSizeScience on how hard candy is made:

Some things of note:
(1) Hard candy is technically a glass made of sugar!
(2) There are three stages of sugar boiling, and the maximum temperature that it reaches determines the physical properties of the resulting candy (I think this is primarily a function of how much water is remaining in the sugar mixture).
(3) If you watch the video, you'll figure out why hard candy always has a ring around the edge. This was something I didn't know.
Enjoy. Perhaps I'll write a post later about what your body does with all that sugar after you eat it. :)

"Life creates [the Force], makes it grow. Its energy surrounds us and binds us. Luminous beings are we, not this crude matter," Yoda explains in The Empire Strikes Back, gesturing to Luke's physical body. This quote is striking because of the apt juxtaposition of the wonder of life with its often disgusting vessel. Like many other animals, we secrete, excrete, expectorate, defecate, flatulate, regurgitate, urinate, circulate, masticate, menstruate, ejaculate, and ventilate. We are filled with gas and feces and blood and guts and mucus and any number of rude things. Life as we know it is possible because of the countless impolite things we do every day. Are we luminous beings? Perhaps, but that's neither here nor there. This blog is about the crude matter that keeps us alive.
