Deoxyribonucleic acid (DNA) is a strange and amazing thing. It carries genes and genetic codes, is so small you have thousands of copies of it, and is made up of a bunch of different parts. With this fun experiment you can make a larger and much more edible version of DNA. To start, you will need two ropes of licorice in your favorite flavor and four different colors of marshmallows. Pick one marshmallow color for cytosine, one for guanine, and so forth for adenine and thymine. You will also need a box of toothpicks. Lay your materials out on a sheet or two of clean paper towel.
