I'm not a complete idiot, thanks. I'm so sorry I misspelled something in a post, ZOMG! I'm obviously retarded!
I wouldn't buy any chemical for an experiment without researching it beforehand.
Silly me, for responding to a post without googling things first.
You guys can be real pricks sometimes, you know that?
Sometimes yes, but this is not one of those times. Coro is expressing genuine concern. This is not a matter of you being "retard" because you misspelled something in your post; it's a matter of you demonstrating unfamiliarity with potentially dangerous chemicals by means of misspelling the names. People are suggesting things like gunpowder and crystal meth and you've taken them seriously. I wouldn't be surprised if some joker provides a recipe for homemade napalm before the thread is over.
You admitted you've never taken any chemistry, but you want to introduce a 10-year-old to it?
It seem to me that you think there's a wall of some sort between "dangerous" chemistry and "not dangerous" that you can avoid if you buy only "safe" chemicals. The fact is, however, that some chemicals that are quite safe in and of themselves can become dangerous when mixed. The bleach and ammonia thing is the most obvious; while I wouldn't let a 10 year old handle either, they're still considered safe for normal household use, but mixed they produce chlorine gas which is lethal enough that it has been used as an improvised gas weapon in battle.
I really think you may want to consider exactly what you're trying to do here. It seems obvious that you're trying to find activities for your son that are both educational and something doable on a fairly shoestring budget. That's laudable, but it might behoove you to learn something about chemistry yourself first. Not only will it contribute to safety, but your son will learn a lot more than he would from just mixing up chemicals.
If you don't teach him anything about the
reason that you can make a volcano from baking soda and vinegar, that's all he learns; "you can mix these thing and get a cool volcano!" That isn't really chemistry. Chemistry class in high school or college is mostly about things like ionic and covalent bonding, molarity, molality, titration, and so forth just to name things off the top of my head. Mixing stuff together is a relatively minor part of it.
