What are some daily things that we are unaware of?

1. Stickers on fruit: The stickers mark the country and producer of the fruit, but it’s the numbers that are the important aspect. If there are 4 digits and the first number is 4, then it means the fruit is sprayed with pesticides. If there are 5 digits and the first number is 9, then the fruit has grown organically, and if there are 5 digits with the first number being 8, then the fruit has been genetically modified.

2. Doughnut hole: In the past, it was difficult to get the edges and the middle of the pie equally baked. So they came up with the ingenious idea of using this shape to ensure equal baking on all sides.

3. The original reason for sunglasses: today it’s obviously to protect us from the sun’s rays. But the original purpose was to protect Arctic people from the dazzling rays of snow. And in 12th century China, they became particularly widespread among judges in order to hide their true feelings from witnesses.

4. Margins on paper: the original purpose was not for extra notes on the side. In the past mice and rats often gnawed on the paper, so in order for them not eat away the information, people started to leave spaces on the sides.

5. Holes in padlocks: People usually buy a new lock when their old one doesn’t work due to rain. However, the purpose of the hole is to put in oil - once done, the lock should be able to open with no difficulty.

What does the number 3 mean on fruit? 😯😳

WOW Very informative since I did not know any of that. I immediately went to the kitchen to check on the fruits: Apple USA 4130, Lemon USA 4053, Avocado Mexico 4225. All sprayed with pesticides. Rule of thumb for me: If it is not to be pealed, wash with soap and water before eating, especially apples. Thank you for educating us Quiz Folks. You're back in my good graces.

I hate stickers on fruit. Peeling them off tomatoes is difficult because the skin is so thin. Same goes for pears. If you have neglected to Peel them off and they end up in your dish, it is most unpleasant when you take a bite.

intriguing . The info on numbers on fruit stickers was unconvincing because it was incomplete and also many stickets on fruit dont contain stickers at all. what they are for is perplexing. surely noone believes oranges are actually manufactured!
