We’ve all seen bananas turn brown. Now we are going to see how to use this browning process to intentionally cause certain points on a banana peel to brown prematurely tattoo pictures. This lets you make pictures on the banana tattoo peel using only a small needle. When done properly, it doesn’t affect the edible part of the banana, so you can still eat banana tattoo later. This is a great arts and crafts project to add a little fun to your packed lunches.
