i saw you can make bombs with soap in a movie once !
Fight Club. They didnt make it with soap...soap was the by-product. I think
I didn't see Fight Club, but there is a common thread between explosives and soap. The old way of making soap involved combining animal lard or fat with lye or potash. A by-product of this process was the release of glycerin from the animal fat. You can recover pure glycerin from the soap-making process after removing the soap, adulterants and residues.
The glycerin can then be nitrated in the presence of sulphuric acid and you get nitroglycerin.
Soaps today don't contain much glycerin unless they are created to be "moisturizing" soaps, glycerin is very hydroscopic. Those 'natural' soaps you can buy from small specialty soap making companies can contain a lot of glycerin. Some moisturizing lotions and creams are glycerin based, but you can buy glycerin by the bottlefull so I don't know why anyone would chose to extract glycerin the hard way.
BTW, dynamite is basically nitroglycerin absorbed by some inert material such as wood saw-dust. The inventor of dynamite was Alfred Nobel, after whom the Nobel Prize is named.
Although making nitroglycerin may not require sophisticated lab equipment, it is EXTREMELY risky unless you know EXACTLY what you're doing, contrary to what some of those 'Anarchist's Cook Book' and similar publications might claim.
They should rename some of those books "20 Sure-Fire and Easy Ways to Blow Yourself to Bits."
