In my last post I explained how to make exploding paste from ammonia and iodine. In some areas iodine cannot be purchased since it's used by the meth heads to make their stuff.
However you can make iodine yourself using an alkali metal iodide and concentrated sulphuric acid.
I normally use potassium iodide because it's cheap and easy to get hold of, (eBay) but sodium iodide will also work.
Add a few table spoons of your iodide into a heat resistant tub and place it into an ice bath. This reaction will get very hot. Using a dropper slowly add concentrated sulphuric acid to your iodide, it will turn into a sticky black paste at first, but keep adding acid until it turns into a black liquid.
Pour your black messy liquid into a large container of cold water and give it a good stir. Give it a few minutes for the iodine to precipitate at the bottom.
Slowly pour off the dark liquid and at the bottom you'll find a thick residue of wet iodine. Scoop this out and let it dry.
Iodine vaporises at a low temperature so leave it to dry in a cool place and not a warm place or you'll have wasted your time.
There you go; iodine has more uses than exploding paste and I'll explain them at some point in the near future.
