Here are a few St. Patrick's Day experiments that might get you and the entire family "Hooked on Science."
 
Leprechaun Slime

Using a few items from the kitchen you can create leprechaun slime for St. Patrick's Day.

Ingredients
  • 1 1/4 Cup of Cornstarch
  • 3/4 Cup of Water
  • 1 Sturdy Stirring Spoon
  • Green Food Coloring
  • 1 Mixing Bowl
 
Instructions

STEP 1: Add the desired amount of green food coloring to 3/4 cup of water in the mixing bowl.

STEP 2: Using the sturdy stirring spoon slowly add the cornstarch to the water.

STEP 3: Add more cornstarch to make your leprechaun slime thicker or add less cornstarch to make your leprechaun slime less thick.

Explanation

Your leprechaun slime is a non-Newtonian fluid, which means it can exhibit properties of both a solid and a liquid. This is due to the nature of cornstarch, which is a natural polymer. A polymer is a long chain of molecules.


St. Patrick's Day Carnations

You can create some St. Patrick's Day carnations by adding green food coloring to the water.

Ingredients
  • 1 White Carnation Flower
  • Drinking Glass
  • Water
  • Green Food Coloring
 
Instructions

Step 1: Fill the drinking glass half full of water and add green food coloring.

Step 2: Cut the stem of the carnation at an angle and place the carnation in the drinking glass for 24 hours.

Explanation

The green water moved up the stem into the petals and changed the color of the carnation from white to red.
