So does what I'm doing work or not? :(

So does the Iodine Tincture and Hydrogen Peroxide thing not work?

Following this though, it should work. o.O I didn't want to go the whole route of pottasium iodide and all of that bs. I'm lazy dammit. :(

....Yet you mix the Iodine Crystals with Ammonia...I smell trickery. :|

I need an Answer! :( Where are all the chemists dammit. :(

So I need to make some Iodine Crystals but I don't feel like filling out a DEA sheet and shit. So I got some Iodine Tincture and Hydrogen Peroxide to make Iodine Crystals but I'm not noticing a reaction, like gas and shit? What the fuck man?

Due to the high heat ignition of Thermite no? Magnesium powder and barium nitrate form a relatively high ignition point, right?

Its for Nitrogen Triiodide. My teacher got super pissed at me for mentioning my project last minute for honors. So I'm having to make everything pretty much. Making iodine crystals with hydrogen peroxide and iodine then letting that dry and mixing it with ammonia to make Nitrogen Triiodide. :\ I wanted to Thermite and Ice...but I don't have any sparklers for Barium Nitrate. :\ Demo is on Monday.

And then at that point to get it at a lower concentration would be to just add water to it, right?

I just bought some ammonia from walmart and now think I wasted money, I was reading up and I guess it's only 2-3%? Where can I find 31%?

FUCKING GOD DAMMIT. Why does something so hot have to be so expensive. :( The sad thing is, I doubt for 10k I could find a human being that attractive.

Took me 4 years to decide on my major, so my knowledge is still limited. Went in the completely opposite direction to, I was all psychology/philosophy based and was like "Oh...fuck..I Have to take all the sciences...fuck"
I have over 108 units or some shit. It's retarded. :(

That doesn't prove instinct, that proves a survival technique where an increase in blood/fear/hormones while being attacked altered the development of the child. That has nothing to do with genetic "memory"

How then is a memory formed without input?

I'm so glad Neuroscience is my major. :D

a thought is something that you think about and then determine whether or not to act on it. An instinct occurs without thinking.

So wait..."I think, therefor I am" but if you don't think, what are you?

>> No.2850643 [View]

A memory? No. Instinct is reflex. Those who breathed lived and passed on their genes. Those who didn't died.

How is thought a naturally occurring process when the only evidence of this we have is humans?

Our brain interprets and sends out information, it's capable of multiprocessing. o.O
