Easter egg hunts are fun for the whole family, but why not kick it up another notch? There are several ways to make Easter eggs glow for an exciting night-time egg hunt or a fun home science experiment.

Steps

In the Microwave

  1. Place the desired amount of raw eggs gently into a bowl with egg dye. Turn the eggs over a few times to make sure they are covered with dye, then let them soak for 5 minutes.
  2. Take the eggs out of the bowl holding the egg dye. Place them carefully on a paper towel until they dry.
  3. Place all of the eggs onto a microwave-safe plate or platter. Place the plate or platter of eggs into a microwave oven.
  4. Set the timer for ten seconds on medium temperature and press start. Allow the eggs to sit there for the full ten seconds, otherwise the eggs will not glow.
  5. Remove the eggs from the microwave oven carefully after the ten seconds. Place them on a table or any hard surface.
  6. Turn off the lights. You will see one or more eggs glowing in the dark. Interestingly, only one in three eggs will have this occur. If it doesn't work, try again with a new batch of eggs.

With Glow Sticks

  1. Crack and flex your glow stick bracelets to activate the chemical glow. Tie each glow stick into a knot or pretzel shape so it will fit easily into the plastic egg.
    • Glow sticks can be obtained - very cost effectively - at art, party, and some grocery/one-stop-shopping stores.
    • The average glow stick lasts six to eight hours, so don't activate them too long before your intended egg hunt. [1]
  2. Open the plastic eggs, add a glow stick and some candy to each, and close them up again.
  3. Hide your eggs outside, or turn off the lights and hide them indoors. Let the glow-in-the-dark Easter egg hunt begin!

With Spray Paint

  1. Lay out the desired amount of plastic eggs on sheets of newspaper or another material you don't mind getting paint on.
  2. Evenly spray the closed plastic eggs with glow-in-the-dark spray paint. Let them dry completely. If you are worried about paint sealing the eggs closed, open the eggs before laying them on the newspaper open-end down.
  3. Open up the eggs and add any candy or prize you like. If you are worried about paint or paint flakes getting on the treats, wrapped candy is always a safe choice.
  4. Let the painted eggs soak up plenty of light. Let them sit under a light bulb or in the sun for at least ten minutes.
  5. Hide your eggs and enjoy the hunt.

Under a Black Light

  1. Paint plastic or hard-boiled eggs with paint that glows under a black light. Using neon-colored eggs may mean you won't have to paint them, but neon black light paint will always glow brighter. [2]
  2. Place eggs near or under black lights, or hunt them down using a flashlight with a black light lightbulb.

Fun Design Ideas

  1. Wrap rubber bands around eggs before dyeing or painting them. After the dye or paint dries, remove the rubber bands. The covered areas will be white and free of paint, leaving cool-looking stripes behind.
  2. Draw on eggs with white crayons before dyeing them. This technique works for raw or hard-boiled eggs (not plastic). The wax of the crayon will repel the dye, leaving white space in whatever shape or design was drawn on the egg.
  3. Use multiple dyes on one egg. If you put an egg into a small glass or tumbler with about an inch of dye in it and just enough width for an egg, the egg can soak just its bottom half in the dye. Let the egg dry, turn it over, and put it white-side down into a similar glass with a different color of dye.
    • You can also experiment using larger, flat containers with shallow (several millimeters) of dye in them.
    • Sit an egg carefully in the shallow dye, so that it does not roll. Take it out and let it dry.
    • This will result in a 'spot' or circle of dye on one side of the egg. Turn the egg so that another area faces downward and soak in the dye. Dry off and repeat until you have created a spotted egg.

Tips

  • You can use any type of dye you prefer; any dye containing sodium citrate will work. In this article, purple egg dye has been used.
  • It is quite easy to get flecks or gusts of spray paint on any and all of your surroundings - consider spray painting the eggs outside.

Warnings

  • Black light paint and glow-in-the-dark spray paint may not be safe for use on hard-boiled eggs that will be eaten. Pay attention to warning labels on paint canisters.
  • Do not eat the eggs after you finish this experiment!
  • This experiment only works with raw eggs. Do not eat the eggs after the experiment.
