Turn a Christmas craft into a science experiment. All you need are pipe cleaners, Borax laundry powder, boiling water and a piece of string. It takes a few hours for the crystals to stick to pipe cleaners. So, you’ll want to let these sit over night. I love these because they are so colorful. Don’t you? You could also use gold or silver pipe cleaners as well so it adds a festival feel to your decor.
