My first Reaction

 One thing I've never done in EVE is reactions. I knew they are used to turn moon goo into tech 2 stuff, and that they're complicated and not doable in high sec, but that's it. I've heard they can be lucrative though so I've been keen to check them out since starting this challenge.

A few things I've learned since researching them:

• Reactions are done using formulae, which are seeded by NPCs all over the place (for 10, 15 or 20mil depending on the "tier")
• These formulae cannot be researched like blueprints, but are infinite runs
• they mostly have 4 inputs, fuel blocks and 3 other ingredients.

MJ- has a reactions structure in system, but apparently different structures only support certain types of reactions. Therefore I've had to head over to the industry park to find a suitable structure. I'm beginning to understand why it's named that. 

Also, when I was looking for a reaction to run I was struggling to find one that was profitable at all. I eventually worked out that while they are run in low/null/wormholes it seems most people must either buy their mats in bulk or import from Jita, and that's where the market for the outputs is.

I was surprised, as I was hoping to run reactions and sell the outputs in null, but it seems there's almost no market for that. I was also surprised at how little money most reactions make from browsing using Jita prices and a null structure. Either I'm missing something or most people are reacting to do vertically integrated t2 production and not selling the intermediates. I am hoping to use my reaction slots similarly to my manufacturing ones, i.e. put in mats get out items to sell.

I did eventually manage to find something with good margins and had them contracted to null:

which looks something like this in the industry window:

This is only a very small run, but my budget is pretty small at this point. My plan is to run this and then export the results back to Jita to sell. 

I feel there's a lot I don't know here, but it's good to get started at least.
