 | How To Make Gun Cotton |
Glad you asked...
You can make gun cotton by taking some fresh cotton wool and soak it in some nitric and sulfuric acids. Let it soak for about a minute then wash with cold water and let the sun dry it. You can find more information here: http://www.publicbookshelf.com/public_ht...
Then again, this answer might help you...
Douse your clean cotton ball in equal parts nitric and sulfuric acid. Allow to cool for one minute, washing in plenty of cold water. Dry in the sun.
