So, I'm building a freeze ray, in a sense, and I was wondering...
What would the easiest/cheapest way to produce an endothermic reaction without using ammonium nitrate? The way I have the schematics so far is that I will have two substances that will blend just before exiting the ray, and therefore will react and freeze the substance it hits. My problem is that it needs to be viscuous enough- i.e, not solid- that it can be dispersed shortly after the reaction. It *also* needs to be cold enough to freeze an organic substance with sufficient liquid in a short amount of time.
Any ideas? Tips? Suggestions?
Keep in mind I'm a high school student who's income comes only from 10$ a pop tutoring sessions and occasionally winning stuff and who lives in the middle of a corn field, which means I am both very very cheap, far away from major cities (so the ability to order online is preferable- I have ammonium nitrate, we use it for fertiliser, but other than that..) and have access to my brother's tools, machinery, soddering iron, scrap metals, etc.
Thanks! :)
