YOU NEED:

• Luminol
• Sodium carbonate
• Hydrogen peroxide, 11.9%
• Potassium ferricyanide
• Agar
• Distilled water
• 3-D casting mold of different fishes (Amazon etc.)
• Lab glassware (Erlenmeyer flask, graduated cylinder, evaporating dish, beaker etc.)
• Bunsen burner, lab hot plate etc.
• Paper towels
• Tweezers

EXPERIMENTAL PROCEDURE:

• Pour 100 ml distilled water in an Erlenmeyer flask
• Dissolve 3 g sodium carbonate and 0.2 g luminol
• Heat the solution until it boils
• Add 1.3 g Agar
• Stir solution until Agar is dissolved
• Let the solution cool down to approx. 80 °C
• Pour the solution into the casting mold
• Let the solution cool down for at least 30 minutes
• Now you can remove the casted fishes from the mold
• Let them dry a little bit on paper towel

• Pour 90 ml distilled water in another Erlenmeyer flask
• Add 10 ml hydrogen peroxide, 11.9%
• Dissolve 1 g potassium ferricyanide in it
• Use tweezers to place one of the fishes gently in a vitreous evaporating dish
• Pour the water/hydrogen peroxide/potassium ferricyanide into the evaporating dish until the fish is completely covered
• Darken the room completely
• You should see a green-blueish glowing fish
