## Explanation:

At an initial glance this riddle seems like it should be easy. As Humans, we recognize plenty of things that deserve to go up and down. But once friend think around it because that a moment, the answer is no so clear, and Eyezak the Riddle Robot knows that. Let united state take a deep dive right into some feasible answers, and also explore why they space not correct. Right here are a couple of things that i think have the right to go up and also down:

A common answer for this can be temperature. Yes, that is clear the temperature does walk up and also down. We have actually all it is in hot, definition the temperature walk up, and also we have actually all been cold, an interpretation the temperature went down. Because of this it meets the criteria. Yet there is a second criteria it has to meet, does the move?

This is a tricky concern on the own, and also probably why there room a few riddles the end there about temperature. The price is ‘yes it moves,’ for this reason no it can not be the answer. Why? Well, in stimulate to understand for sure that the temperature has changed (and that is not just your tardy of the temperature), you have to measure it. This is an important distinction because everyone knows once you are sick, things can feel really warm or cold, and not in reality be warm or cold.

You are watching: Things that go up and down

So we understand measurement is a need to recognize it changed. If you measure it though, you have to have a means to show the value of the temperature number. This needs an tool of some sort that either shows a reading using a mercury based indicator or screens a number that represents the temperature.

In the instance of the mercury indicator, the mercury is physically relocating up and down inside a self-contained tube (because mercury is actually really poisonous substance). Thus it is moving. If you screen a number instead, the action of that number changing on the display or analog dial, is in reality movement. As such again, this cannot be the answer come this riddle because it is in reality moving.

Elevator

We have all ridden in an elevator before because they are way more convenient than the alternative. You just walk into it, stand inside, fight a button, wait prefer 20 seconds, and also voila girlfriend are now 100 ft higher above the ground. Yes obviously, the goes up and down. If the didn’t go up and also down, no one would usage it, especially civilization who live over the 10th floor.

The inquiry is, walk it in reality move? Yes unfortunately it does. When you room inside it, the elevator physically move up and down. You may not feel it, yet you actually relocate quite easily while inside it, between five and 22 miles per hour actually. That is about the speed of your median casual bike-ridder, only you are moving up and also down instead of side to side. So, this would not prize the Riddle Robot Eyezak and also his riddle. Let’s move on.

Helicopter

Helicopters are very cool! You have the right to go up and down in a helicopter, completely vertically. The is in reality the very nice of a Helicopter over a Plane. V Planes you require extra room in front of you, so friend can slowly climb up in altitude v a low slope. Helicopters enable you to rise in altitude in ~ a an extremely high slope. Friend require nearly no, if any, frontward activity to climb.

Does it move though? correct it does. When you ride in a Helicopter, that physically transports girlfriend from one location to another. In enhancement the auto itself it additionally moving, not only as a whole, but there space several components of the copter chin that relocate independently, favor the blades and the rudder. Based on those facts, Eyezak is still winning, because we have actually not uncovered the answer come this riddle yet. Moving on… how about a coin!

A Coin i Flipped

Sometimes the only fair way to decide an outcome is to leaving the result totally to chance. The most common method of law this, as soon as there are two various options, is to “flip a coin.” To perform this, you take a coin from her pocket, or her piggy bank, organize it on height of your fisted hand, with your thumb positioned directly underneath it. Then you flick your thumb upwards. As soon as done right, the coin will start to turn head end heels and go vertically up and also then down earlier into your open up hand.

This plot of paris up and then landing under again is actually thought about moving, as the thing physically changes location as it moves v the air. You might have decided to “eat out” or “cook” because that dinner tonight, yet you did no beat Riddle Robot Eyezak yet v this answer, due to the fact that it does not fulfill all the criteria of our riddle. Us have more more shoot at getting it right.

Stairs

Stairs room those constructs you uncover in houses and also buildings that permit you come walk forward, while increasing slowly. Each set of stairway is make of sequentially greater miniature platforms, barely huge enough for one foot to land ~ above it, called “steps”. This steps, as soon as strung together in order, permit for a low slope increase from one floor to another floor in a building. That is a well known truth though, that most human beings hate stairs, with a passion, and also opt to use options like elevators instead.

When friend look in ~ the stairway from one of two people floor, the stairway are always stationary, and also they generally contain no relocating parts. If you decide to “take the stairs,” while in reality you together a person do move, the stairs are constantly still, and also unmoving. You room actually moving of your very own volition and power. As such the stair themselves are not relocating at all. This looks prefer it is a promising answer to conclude our riddle.

To recap, the stairway to affix two floors in a building in a largely vertical fashion. Therefore we deserve to conclude the they “go up and down.” They also do no physically move themselves, and also any entity, it is in it you or her dog, that offers the stair are moving under their very own power, without any type of motion-aide native the stairs at all. Therefore, the is safe to conclude that part Stairs actually fulfill both answer problems for our riddle. I bet Eyezak our Riddle Robot is walk to be mad at us for figuring it out.

## Background:

Stairs deserve to be called many things including “stairs,” “staircase,” “stair well,” “stairway,” “flight that stairs,” and also many, numerous other names. Their basic role is to make a vertical distance much easier to travel, by simply breaking it right into smaller distances that are straightforward to take through a single footstep, referred to as “steps.” friend can find them inside and outside, usually enabling the user to more easily climb in between two different elevations.

For security reasons, many stairs have actually extra components that avoid the users from hurting themselves, which usually take the type of a guard rail, handrail or decorative banister. These safety and security mechanisms deserve to be make of sensible materials, v very tiny regard because that design, or they deserve to be make of extremely an elaborate materials and serve no real sensible purpose other than aesthetics. One of two people way, they do a nice enhancement to the staircase.

They deserve to come in many forms from a simplistic directly shot 2 landing stairway, just connecting two elevations v a single stretch of stairs. Friend will also find “switchback” format stair wells, which combine winders and landings to do consecutive quick groupings of actions that permit the user to move in alternate directions when they rise to the top. Then there room spiral case that make the user constant walk in a circle to get to the top.

Stairs have been a commonplace device for transforming elevations because that a long, long time. There are records that show stairs that predate early civilization as far earlier as ancient Egypt. Humans have been making and also using stairs due to the fact that basically the start of time and recorded history. Lock have come to be such one integrated component of human being existence the you would certainly be difficult pressed to uncover a culture that walk not use them. Your origins have nothing to carry out with this riddle, regardless of the reality they room the answer.

Hopefully friend enjoy finding out these brand-new things. The Riddle Robot Eyezak, Puzzle Master, does not really treatment if you know these things. But the more you find out today, the simpler it will be to fix future riddles from that tomorrow!
