White Vinegar is one such products. It has been said that vinegar has 1001 uses, I believe that it has more. It can be used to preserve food, a remedy for jelly fish and bee stings, deodorizer, stain remover, cleaner, beauty aid, in the laundry, a cat detourant, and the list goes on and on. It is believed that Hannibal used vinegar to clear large rocks that blocked his army's route. Now that's what I'm talking about!
On our adventure, we will be carrying vinegar. Do you know of any other such products that we should have on our list?
