For all your food preserving needs
Even the French are taking advantage of it!
This invention changed the way people lived back then because it helped the military initially. It later helped settlers because they could store their food instead of leaving it without protection. The mason jar jump started the making of other canning processes we use today for foods such as sauces, pickles, relishes, fruits, and tomatoes.
The first persuasive technique I used was Testimonial, when a famous person gives a direct quote. I used it because I thought people would be more likely to buy the product if a person as famous as Napoleon were to buy it. I also used Bandwagon because if people all over the land were eager to buy it then it would be purchased more.
