Here’s how to make Green Slime, just like the Nickelodeon Kids Choice Awards. Ingredients: 6 large packages of Jello, 9 lbs of flour, 8 ounces baby shampoo, 1 small bottle of green food coloring, 1 1/2 Gallon of water. Mix the Jello, half of flour and 1 gallon of water. Wisk until lumps are removed. Add remaining. Continue to add water until you reach desired slime feeling. Add baby shampoo and food coloring. Stir until slime is green. Makes 3 gallons of slime.
