How would the world work if you were bigger? [closed]

Question

Suppose there was a family who were suddenly scaled up to the size of the ones in Gulliver's travels, about 72 feet tall, 12:1 proportionally scaled up.

For the purposes of the question ignore the impossible Biology of such people, This question is only about the effects someone would notice if they were suddenly scaled up?

Also assume that their entire house is also scaled up along with them.

The Question

What would a person who has been scaled up start to notice in their immediate surroundings, how might things act differently to a giant person?

Ex: things seeming to fall much faster and making a larger impact on the ground , Things seemingly break more easily, water acting differently.

Additional info

• liquids are not scaled up, only solids

• They do not go outside, they are only noticing the effects inside the house

• Solids that are scaled up are only scaled in size , not strength

Edit:

• This question is only about the environment, not the giants themselves. I want to know how things might act differently on larger scales

• Assume the house has regular items almost every house has (Fridge, Sink, ect..)

Answer 1

Well, the first thing they'll notice is that there's no running water, because the municipal pipes will not have "grown" with their house. In light of this, I find the "they do not go outside" constraint a little silly.

Power lines will also, very likely, have snapped, so their appliances will have stopped working. In addition to this, electronics don't work flawlessly when scaled willy-nilly. The material properties of various circuit components will probably cause them to fail spectacularly, and they now have giant batteries attached, don't you know. So now their house is probably on fire, and there's no running water, or working phone lines.

And so, assuming they've now stuck their head out the window in an effort to figure out what's up, they'll realize that they're most likely doomed to starve to death. Solid items scaled up, so the food in their pantry has also increased in size, however, once that runs out they're stuck with measly, human-sized food products. And at 72 feet tall, even a whole cow is only a small snack.

Answer 2

You can ignore the physical realities of your body's biology, but you can't ignore the fact that everything else around you has a mass that increases by $12^3 = 1728$ times while you grow 12 times in height. Your 36 foot tall dinner table that used to weight 50 lbs now weighs 43 tons, your chef's knife 800 lbs.

Even if you assume that your strength is scaling up proportionate to mass (not height), the strain on some of the materials in your house might be too much to bear. For example, I think there are a lot of table designs where wood, no matter how thick, could not support so man tons of weight on legs 50 feet apart or more. I think they would notice because random household items would collapse under their own weight.
