We have a phenomenal science experiment for you to complete with your little one during this spooky season. Although this activity does take a little more time and effort than some of our others, the results are absolutely AMAZING. This experiment allows your child to learn how salt and ice react to one another while hunting for Halloween treasures they planted themselves. These Halloween hands are a two day experiment and take a little patience, but I can guarantee your children will LOVE every minute of it. It will definitely be worth your while!
