Straw weaving. This is fun. I did this with all my fifth grade classes this past school year. They loved it! Sucking the yarn through the straws got a lot of giggles! :) Easy project! "Over, under, over, under...go around & do the same thing again on the other side!" Tip: Don't get the straws that bend at the top!
1/2 Tablespoon of oil and 1 teaspoon food coloring on top of small amount of water in shallow pan. Lay heavy paper (cardstock) on top and wait until you see oil coming through back. Lift paper and see your design. Can drag toothpick through colors to make new design.
