Probably way safer security-wise than a search on the Internet, unless using a computer at the library. Kids everywhere have always experimented with explosives, and always will. Mostly boys, however. My mom was always upset with me blowing up toy cars, etc., nearly took my fingers off a couple times. My grandfather used to dry homemade gunpowder on the stove (long before I came along, would not want to see that). Amazing that house-hold items like baking soda and cotton can be transformed by heat and mixing with other ordinary home chemicals.
When I waas a kid, I had a blessedly free access to blasting caps, fuses and dynamite sticks. We learned lots of stuff.
When my son was in ninth grade, a kid in his Spanish class, was bragging about having made 5 pipe bombs, using the book that he took out of the library, and said that he was going to use one on the school library, one on the cafeteria, one on our house because we lived in a gated golf course community, and he was taking suggestions for the other bombs.
I called the school and the school called the police and took the bombs from the kid.
