How do you call the tool that divides customer’s goods in a supermarket?
Everyone has used these helpful tools at the checkout of a supermarket. They’re quite effective preventing cashiers from accidentally scanning the good of another customer. Standing in line at the checkout you grab one of these little things to state: “These are my goods.” The fascinating thing is that most people really do not know what these things are called. Or maybe they don’t believe they know as the answer is very (too) simple. These “things” are called checkout dividers or grocery dividers.
If man is an advancement of the ape, why are there still apes?
First and foremost, it’s the same with every “model”. Although there are new ones out on the market, old models are still produced and sold. Of course man evolved from the ape and sometimes this is still obvious today. Anyway, man’s ancestor was an ape called Hominini. The Hominini comprises seven genera. Six of them are already extinguished and only one exists until today: homo, i.e. man.
Of course there are still apes these days but not the ones that were man’s ancestors. So, the apes that man developed from have nothing to do with the apes that still exist today.
How do you know that your invisible ink is empty?
Invisible ink is not really invisible, Mr. Bond. It rather becomes invisible when it is applied to paper. To understand how this works you have to know what you can use as invisible ink: vinegar or citric acid. Moisten the tip of a feather, tooth pick or whatever with one of the liquids and write your secret message on a piece of paper. As soon as the paper has dried it will look as though it has never been used. By ironing the paper the message will become visible. Ergo: you can see when your invisible ink is empty.
If you want to know why the message becomes visible read on:
Both vinegar and citric acid are acids that dissolve the paper wherever they are applied. Through heating the paper this chemical reaction – called thermic decomposition – is quickened. The result is that the paper becomes brown where there is acid. Thus, the message becomes visible.
If you choke a Smurf what color does it turn?
Whenever people are choked or strangled their skin turns blue. Choking someone leads to a missing gas exchange causing hypoxemia, i.e. the oxygen partial pressure in the arterial blood decreases. Therefore, the skin turns blue.
For the sake of answering this question we have to assume Smurfs were real (I apologize beforehand if I have just destroyed someone’s world view).
A Smurf is blue by nature. So maybe it turns a deeper shade of blue if you choke it. The answer is no. I went on a long and hard journey through dense forests and deep marshes to get to the Smurfs’ village and choked the first Smurf I met along the way. It did not change color.
Seriously (more or less), look at the picture of a Smurf. What catches your eye immediately? Correct, Smurfs have no necks, so you cannot choke them and so they cannot change their color.
