Toothpick star experiment ⭐️ age 4-8 ⭐️ Super easy experiment you can do with 5 toothpicks and some water. Break the toothpicks in half and arrange with centers together in the middle. Then add about 5 drops of water to be middle and watch the star form. As the wood absorbs the water the fibers try to straighten themselves forming the star! Very cool! 👍🏻
