How to Write Science Based Magic
How to make your world's magic make sense!
Magic in itself makes no sense, which is why we call it magic. With that being acknowledged, many authors have created their own science to the magic that they have come up with. There is no rule for your magic having to have rules to it, but the reader often will find your writing more interesting if there's lore for them to understand. It gives the fandoms something to argue about, meaning they’ll talk more about it.Â
There are a few classic forms of magic that you’ll see, so I’ll go through each one that I know and explain how you can throw some logistics into this world you’re building. I would like to make a disclaimer that none of this information should be used in real life by someone who's not a certified scientist in a lab with safety precautions. If you try these things in real life, you’re an idiot and then I’ll have to take this down. Now let’s get into it!
First up is a well known classic and what some people would call elemental magic, which includes fire, ice, earth, air, and then you can even add dimensional, light, dark, forbidden, lunar, etc. if you want to get spicy. For these kinds of things, you can learn what elements you actually need for different reactions.Â
One of my favorite examples is something that probably got me on a watch list for researching, and I called it an explosion bomb spell. It’s when a thermite is placed on top of ice and ignited with the help of a flame, as the ice is immediately set on fire which causes a large amount of heat to be released in the form of an explosion. This would be water, earth, and fire magic.Â
The next example is what I called a fire breeze, which is a reaction between diethyl zinc (chemical element) and water, air, or anything else that can accept 2 electrons OR one proton. Another is one that is debatably worse than the bomb one is called land mine, which is the careful reaction of iodine and ammonia, by reacting iodine with an aqueous ammonia solution. The result is an extremely sensitive contact explosive.
Another form of magic is alchemy, which is defined as the medieval forerunner of chemistry, based on the supposed transformation of matter. I’m going to tell you a bunch of alchemical reactions you can use in your stories, which includes some kind of chemical or element being mixed with heat, physical contact, etc… Since this includes so many possibilities, I’m going to include 4 of my personal favorites.Â
First is Nitrogen Triiodide and physical contact. The compound is formed through the careful reaction of iodine and ammonia, by reacting iodine with an aqueous ammonia solution. The result is an extremely sensitive contact explosive. Small amounts will explode with a loud, sharp snap when touched even lightly with a feather, releasing a purple cloud of iodine vapor.
Next is Ammonium Dichromate and Heat, which when ignited decomposes exothermically, producing sparks, steam, and nitrogen gas, like a mini volcanic eruption. It also produces green chromium (lll) oxide "ash." Ammonium dichromate has been used in pyrotechnics, photography, and lithography. It can also be used as a mordant for dyeing pigments.
Next and one of my personal favorites is potassium chlorate and sugar, which can be represented by a gummy bear experiment you may or may not have heard about. Gummy bears would be dropped into potassium chlorate, then a drop of sulfuric acid added as a catalyst, and you then get two chemicals that are reacting violently with each other. They release large quantities of heat energy, forming a spectacular purplish flame, and a great deal of smoke in a combustion reaction.
Finally I have NaK Alloy, a metal alloy that is formed through mixing sodium and potassium without air, and water. The heat given off by this reaction rapidly melts the sodium and potassium and is often enough to ignite the hydrogen gas produced. It might go off in air normally, but when you add water you get a much better explosion.Â
Our last form of magic is going to be what I refer to as basic matter creation, which basically consists of each person having a specific type of magic. It’s similar to what you see with the magic books in Black Clover, or the Chakra you see in Naruto. It doesn’t have to be genetic though, and you can form it out however you want and still get some science in there.Â
With this form you want to use more physics and chemistry, as these are quite literally the sciences of all physical matter. I have to say that this is quite literally my least favorite type of science based magic, but I’m still going to explain it to the best of my abilities. I’ll start with stating the states of matter, including the ones you don’t see in your day to day lives.Â
Solid has a defined shape and volume, liquid has a defined volume but no defined shape, and then gas lacks both defined shape and volume. Those are the three you’ve known for your whole life, as it defines the surface world that lives around us. The next few are more complicated and will include detailed descriptions, so take that as you will.Â
Plasma lacks both defined shape and volume, however the particles are charged electrically and are separated by longer distances. An example of plasma would be lightning and the aurora. Next is glass, which is an amorphous solid intermediate that is between a crystalline lattice and a liquid. It’s only occasionally referred to as a different state of matter though.Â
Next we have a superfluid, which is a secondary liquid state that only occurs at absolute zero, meaning it has zero viscosity. This means it moves around with zero friction, making it faster and lighter than your average liquid. Next is dropleton, also known as a quantum fog, because it has electrons and holes that flow much like a liquid. I believe this might include the fog you get from incense that flows like water, but I can’t find any evidence to confirm this.Â
The last form of matter is actually the state of not being matter at all! It’s called gravitational singularity, and it’s used to describe the center of a black hole. It is not a state of matter, but it has to be noted because it’s still an ‘object’ formed by mass and energy that lacks matter.Â
Now that you know this, you can classify your matter based magic by these standards, or you can throw this information away and do it your own way. It doesn’t matter how you write your story, because at the end of the day it’s YOUR story. I might be biased though, but I love a fantasy story that has a bit of realism. It’s the type of surrealism that some readers get a kick out of, and it’s also something other readers might hate. If you decide you want to use it, though, you know where to come for the information you need!
