[custom_adv] Why do stores put oranges in red mesh bags? The reason is aesthetic, simply because the red mesh bag makes the oranges appear more orange and therefore more appealing to the buyer. The orange peel might not actually be as orange as the bag makes it look, and the red color just enhances their vibrancy. The same trick is often used with other citrus fruit, like tangerines, grapefruit, and even lemons. With lemons, they are put inside green or yellow mesh bags, so they appear more yellow. [custom_adv] Why do chocolate bars have wavy lines? The way most candy bars are covered with chocolate is by being out on a conveyor belt while a veil of wet chocolate covers them. These belts have very specific patterns at the bottom, and as the bars are moving on them, the chocolate starts to cool. As a result, they are left with the pattern of the belts on their bottom side and very often with a less noticeable pattern on the top side. [custom_adv] Why do egg yolks turn green when cooked? If you want a hard-boiled egg, it’s quite easy to end up with a green ring between the white and the yolk. This isn’t something that should worry you, since the egg is still perfectly safe to consume. This happens because you boiled the egg for way too long. And in this case, the hydrogen in the egg white combines with sulfur in the yolk, resulting in this green color. [custom_adv] [custom_adv] Why does chocolate turn white after a long time? If you’ve kept a bar of chocolate in your cupboards for a long time, you might have noticed that it gets discolored. It looks like a white shadow has covered the chocolate, and it doesn’t look appetizing anymore. However, it’s nothing to worry about, and you definitely shouldn’t throw the chocolate out since it’s perfectly safe to eat. It’s just that through time, liquid fat like cocoa butter migrates through the chocolate and crystallizes on the candy’s surface. [custom_adv] Why don’t supermarkets have windows? The trick is very simple: supermarkets want to keep you detached from the outside world, so you can shop for longer. Without windows or clocks, you have no idea what time it is and what the weather is like outside. It could be raining or snowing, and you will have no idea about it, since the nice music and products around you keep you occupied. But also, windows are much more expensive, and stores prefer buying shelves that are way more useful to them.
