Halloween fun!


Need some cool science demonstration to do for Halloween? Look no more! All you need is a raw egg, vinegar, and green food coloring. You can call it "Alien Egg" or "Monster Egg". Have students make predicitons of what will happen when you put a raw egg in vinegar. You can even talk about acides and bases. "What is vinegar, an acid or a base?" "What do acids do?" "What will acid do to our egg?" Place the raw egg in a beaker or glass of vinegar. Add food coloring and wait. Students can make several observations. After 24 to 48 hours, the egg shell will be gone and you will have the coolest looking "alien egg" ever! Your kids will be amazed!
