Saint Patrick's Day

pot of gold at the end of a rainbow


St. Patrick’s Day is a great time to go “green” with chemistry. Turn your house water green for the day; burn green flames; make green goo; or have a green breakfast.

  • Gold Pennies
    Make leprechaun “gold” as you learn about alloys and turn pennies from a copper color to silver to gold.
  • Fried Green Egg

  • Glowing Flower
    Give your bouquet a secret St. Patrick’s Day glow by allowing flowers to absorb fluorescent ink or tonic water.
  • Gluep—Solid or Liquid?
    Whip up a batch of green goop by adding green food coloring to the standard gluep recipe.
  • St. Patrick's Day Science
    Turn science store products like UV beads into a “blarney bead” bracelet and superabsorbent polymer spheres into “leprechaun eggs”.
  • Colored Flowers
    Use green food coloring with this classic capillary action experiment to create flowers with a St. Patrick’s Day hue.
