Beth Harris, Raleigh mom and science educator, returns today with a really fun and easy experiment for kids to try - invisible ink!
All you need is a piece of paper, milk with some amount of fat in it, a cotton swab, pencil and sandpaper. Watch the video to see how it's done. And check out Beth's website where she shares more invisible ink recipes and the science behind why they work.
