So, dragons here use aqua regia (an acid that dissolves even gold) as their breath weapon. This acid is made up of the dragon's stomach acid and some nitric acid, stored in a separate organ. On to...
In a specialised organ, the Vesica Spirite, which in function and makeup resembles a cross between the Ventriculus and the Vesica Biliaris, the animal creates and stores potent spirits by the me...
In Hungarian, there is a new-ish folk-song sung by school-children who dislike school whenever it snows to the tune of Twinkle, twinkle, little star: Hull a pelyhes dinamit, Robbantsuk fel...
The Old Ones build continent-sized bunker complexes to protect themselves from the enemy, which followed through the cosmic ocean. The Hunter succeeded easily despite their efforts and their corpse...
The limpet teeth's microscopic structure is analogous to man-made short-fiber composites. Its strength depends on the direction of the force, relative to the orientation of the fibers. https://www...
"Aliens used uranium and plutonium to generate energy for thousands of years. However, by the time they got into space exploration, they've used up every last bit of it. That's why they'll have to ...
For complicated reasons our hero's blimp in the Venus atmosphere at an altitude of 50 km gets a tear in it and sunlight floods inside (there is no gondola, the blimp is a semi-ellipsoid of breathab...
My question: What is it that needs to be improved or added to the human body so that it can withstand critically (fatally) low and high (if, my genetically modified person is underwater or a very d...
This question is related to Deadly, Heavier than Air Gas, and Is a world with two different types of air possible? but has several different criteria. I've also looked at https://chemistry.stackexc...
Question: does a liquid or gelatinous substance exist that once outside a body could solidify and be hard enough to be used once as a tool? The setting is low fantasy without magic, yet with creat...
Previous parts here: Creating a scientificly semi-valid super-soldier, part 1: Skeleton Creating a scientificly semi-valid super-soldier, part 2: nervous system Creating a scientificly semi-valid ...
How could blue soil exist, in a realistic earth-like world. The world may even be earth. First off is it even possible - could soil like this exist given the requirements below? (if not then why?)...
Magical fire is often depicted as flames. To get fire and flames the right mixture of oxygen, fuel and heat is needed. Assuming that the magic only provides the heat, there are only two chemical re...
I have an alien species similar to a caterpillar, the original idea was that the creature could eat different materials, digest them then combined with a very sticky liquid created in its body, it ...
Is there an example of substances interacting with each other in the following way? A is a lethal substance, killing within minutes to hours when orally ingested; anti-A is an antidote for A (or ...
Ok, to be honest, I don't believe about dragons having a special bladder or organ that stores up gas (especially methane) and having flint-like teeth or whatnot, or even having six limbs. Here's m...
Have a creature from a dream. It's a carbon based humanoid creature partly made of the mineral olivine. Could there be any reason it might contain this mineral? Perhaps a show of health - the more ...
How fast could run a humanoid being, how much damage could resist, how much weight could lift, how strong could hit, under the indicated evolutionary conditions? is there a limit? I have always tho...
Would it be possible to have an organism to be based on alcohol, rather than water? Complexity does not matter, but a complex organism would be favourable. their environment would be in oceans of i...
I've been using this helpful diagram a lot for worldbuilding. Now I came to think about the fact that helium is more massive than hydrogen, thus a scenario where hydrogen escapes, but helium is ...
Imagine a Mark Wattney-like scenario, only on Titan and involving a decent-sized base being isolated instead of a single person. There is not, and never has been, the possibility of growing potatoe...
I made an organism called the Skarlix for a art/xenobiology project called Sagan 4. The Skarlix is a eukaryotic, somewhat amoeba-like organism that "eats" various metal compounds and "breathes" (o...
I've been working on the anatomy of my boron based life using alternative biochemistry. But I've recently came across a problem that I can't solve on my own. In oxygen breathing life on earth, the ...
I want to know whether there is a way to make coins that are "swimmable" in the fashion of Scrooge McDuck. My inquiry is based off this Family Guy meme from Pinterest The coins don't necessari...
Gods occasionally visit the mortal realm for particular reasons, such as certain festivals or to do battle against demonic forces in an invasion. In the case of the latter, a god has to be careful ...
I'm basically searching for an ATP that can be used to supply cells and also have its energy extracted efficiently into a basic form of explosive material (the stronger the better) without a lot of...
i want to make an armor made of liquid, for example like dew accumulate and attached to the person or just dip into water and the water attached/carried on (just example), but it also condense the ...
SPOILERS FOR ATTACK ON TITAN, READ AT YOUR OWN RISK... Hardening, or Titan hardening is an ability posessed by certain types of titans in the anime Attack on Titan. Since the setting has rifles ...
I've got a lunar colony that was set up to be self-sustaining before a collapse of life on Earth. The colony has survived on its own for several thousand years through a period of technological reg...
Energy released in an exothermic reaction depends on bond energies of reactants and products. Since molecular bonds are electric in nature, at the first glance, increasing Coulomb's force should in...
as the title, what materials or ingredients in modern gunpowder that if change to be expensive or rare to get, can ruin the evolution of advance gun or can turn modern gun obsolete or undesirable ?...
Not exactly indestructible, at least after flying to certain height it may pop out. I mean something like the bubble is as hard as stone or steel but still elastic and light to float like bubble, ...
as the title say my question is: What planet composition is need to have giant human that make earth human similar in comparison to ant size to them? i know realistically and probably its imposibl...
Carbon dioxide turns supercritical above a pressure of 73 atm and 304.25 K (31.10 °C). The surface of Venus fullfils these conditions. The density of the air at the surface is 67 kg/m3, whi...
I've been recently looking into alternative biochemistries for life and the environments were these could be found. I already asked a question about how ammonia oceans might form a while back. Toda...
Iron planets are planets which lack a significant mantle. These planets are essentially lone planetary cores. Since water and iron are unstable together iron pentacarbonyl and other exotic metal-ba...
Aquatic races are usually assumed to be stunted in technological development by the inability to create fire or forge metals. But what about doing chemistry at all? The development of chemistry i...
I have read unlimited news in which a person has knowingly laced the food items of a person with something to make him mad to fulfill an ill purpose like succession of property, frustration due to ...
I'm looking to design one of my warring planets around organolithium chemistry with seas and precipitate primarily composed of a clear organolithium solvent liquid - possibly ammonia. I've searched...
In an alternate Earth, a mass extinction wiped out a percentage of the most successful phylum ever--Arthropoda. All that survived of the class Arachnida were the really small varieties--the ticks,...
I'm working with the idea of creating a sun made out of pure gold. Of course, this would be completely man-made. Why would anyone want to do this? Because I want a cool concept like that in my stor...
I've been thinking of the idea of creating and adding an alien species that's antimatter-based (being from a universe where antimatter became the majority instead of "normal matter"). However, I'm...
A group of scientists discover a heretofore unknown species of fungus. unbeknownst to them, let's say it is of extraterrestrial origin but it operates very much like certain fungi on Earth (e.g. op...
The following scenario takes place on Earth, sometime in the next few decades. An unethical biotech company has developed a deadly bioweapon that uses humans as a vector, almost like a suicide bomb...
I'm interested in coming up with a plausible agent of destruction, virus or fungus or engineered weapon or what have you, that could conceivably wipe out a majority of the human race. What physical...
How can Bronze Age people make hazmat gear for chlorine trifluoride? The ClF₃ is produced biologically, just as fruits produce acid or capsaicin. This alternate world just happens to have bacte...
I'd encourage you to take about 4 min to read the whole post. Multiple masses of parabanic acid appear at random around the world (but see Context and constraints), displacing any matter in their ...
Rust Monsters are one the few original monsters in D&D that didn't fade into obscurity. Probably because of their ability to turn James' favourite metal items into dust. Rust monsters are ba...
I like the idea of elves having a distinct weakness against iron, to the point where they're intensely scared of it and can't stand the touch of it. My question is: Assuming the Elves are mostly...
Lately I have been thinking about possible forms of life on planets that would have radically different experiences than here on Earth. I was wondering if life based on transition metals was possib...
