For anyone that maybe intrested in some basics of chemistry this book can really give you a great starting point. If I recall correctly I believe this book may have been provided with old chemistry sets but don't quote me on that. I was also told that the book was pulled due to a few of the experiments it has in it, due to them being dangerous to youngsters or even those with little knowledge of chemistry. If you do not know much about chemistry there may be a few experiments in this book that you really don't want to follow the advice of what is being said. There are things that could potentially hurt you. That said if you use some common sense this can be avoided. This country U.S Atleast, seams to me that people just don't use common sense and need to have the government or some law agency make these decisions, laws so one does not injure themselves and if you ask me I wonder what the fuck is it with some people. For instance where I live and hopefully where you do to it's against the law to talk on the cellphone while driving. Now if your a dumb fuck you may have to learn this by getting a ticket. Common sense should tell you that if one is driving say a hunk of steel that weights thousands of pounds and others are driving them next to you and in front of you, behind you then you need to know what is going on at all times. If you are unsure just ask someone ask don't be afraid to it's how you learn. I don't get why people in forums talk shit if someone asks them a question cause everyone has to learn and no one can learn without asking questions so please ask and stay safe.
