This little girl made a simple science experiment for school. She took a store bought sweet potato, put in water, and waited to see how long it took to grow vines. But the vines never grew. She went to the store and they told her that the potato is sprayed with a chemical called Bud Nip, so it would never grow. The store worker told her to try the experiment with a organic sweet potato. Interestingly, the organic potato grew vines. Which potato do you want to feed your kids?
