What Happens If We Throw an Elephant From a Skyscraper? Life & Size 1
Why Worldbuilding Stack Exchange recommends it
Worldbuilding Stack Exchange users link it when answering questions about scaling creatures up or down, where they need a quick, visual explanation of the square-cube law and its limits on strength, flight and survival.

What it is
A Kurzgesagt animated explainer on how body size shapes living things, using the square-cube law to show why falling animals, insects and large creatures behave so differently. It is the first video in the channel's Life & Size series and runs about 6 minutes 40 seconds.

This answer doesn't refer directly to bacteria but it might still help. There are some insects that no possess gills and yet are perfectly capable of breathing underwater. Through using microscopic hydrophobic hairs, the insect is able to create a barrier around itself where the danger of water with its nasty surface tension becomes negligible. But it goes a step further, both carbon dioxide and oxygen are able to diffuse across this barrier allowing the insect to breathe easy . Hope this helps! [this video]

What I would like to know is how this creature's musculature would compare to ours regarding strength, more specifically lifting and carrying weight. Yes, it would be comparable. So, let's look at the square-cube law another way: the larger something is, the slower it is in all areas relative to its size. It's metabolism and reaction times slow down, its top speed slows down, etc. It also lifts less mass relative to its own body weight. So scaling a mantis up to human size would result in a mantis with human strength, human speed, human reflexes, and so on. Keep in mind that the average human weighs 45 - 50 kg, and most cannot lift more than half their bodyweight without specifically trainin

Very nice youtube that might help and give some insight into how small creatures (insects and such) experience air. Adding more atmosphere can make the effects for insect beneficial. [this video]
Recommends John · 2021-02 · Worldbuilding Stack Exchange · on “How would small humans adapt their architecture to survive harsh weather and predation?”
keep in mind humans that size is pure fantasy you can't just scale animals, these humans would freeze to death in minutes in even mild weather, the square cube law is a pain. so you need a large suspension of disbelief just to start. These two video should give you an idea of some of the problems. [this video]
Recommends Globin347 · 2021-05 · Worldbuilding Stack Exchange · on “Would a prehistoric Dragon be Bigger or Smaller?”
Questions about dragons get asked every now and then. First, about oxygen levels: To my understanding, that only applies to the carboniferous, the age of giant insects and superforests. The dinosaurs lived with a similar oxygen level to what we have today. Also, Flying animals can only get so big because the power-to-weight ratio of muscle becomes less favorable with size. This is the square cube law. This video [this video] provides a quick overview. In any case, flying animals are hit very hard by the square cube law, so their size is especially restricted. The giant Azhdarchid pterosaurs from the cretaceous were probably about the limit, and they had to make some big sacrifices to get into the

I'm a budding mad scientist working in my backyard, with access to about 10,000 dollars' budget, a genius aptitude for genetic engineering, and garden tools. I've got some kind of backstory to avenge, and long story short, I've decided to unleash an army of genetically engineered monsters on the world. So what can I make? I don't have any future tools, or even the most cutting-edge gene-editing equipment (unless you think I could build it?), but I have no moral reservations about stealing, murdering, etc. This question might sound a little too open-ended, but what I'm specifically looking for is: Something deadly: it can kill humans significantly better than humans can kill humans. So, train
