萬聖節即將來臨,這裡有一個來自ByteSizeScience的影片,講述硬糖是如何製作的

(1) 硬糖在技術上是由糖製成的玻璃!

(2) 糖的熬製分為三個階段,達到的最高溫度決定了最終糖果的物理性質(我認為這主要是糖混合物中剩餘水分多少的功能)。

(3) 如果你觀看影片,你就會明白為什麼硬糖的邊緣總是有一個環。這是我以前不知道的。

請享用。也許我稍後會寫一篇關於你吃完糖後身體如何處理所有糖分的文章。:)

"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.
