Here are some spooky little Halloween decorations made from hollowed out eggs and LED candles. These "pumpkin eggs" are easy to make, inexpensive, and unlike carved pumpkins, they won't rot. You can place on your window sill on Halloween night or use it to decorate your desk at the office and impress your co-workers.
These are Halloween versions of a the [[https://www.instructables.com/id/Eggcellent-Night-Light!/] Eggcelent Night Light! and the https://www.instructables.com/id/LED-Ball/ LED Ping Pong Ball.

Step 1: Materials

You will need:

Egg(s) or ping pong ball(s)
Needle/awl for hollowing out egg
Orange Easter egg dye (or use red and yellow food colouring with white vinegar- you will also need a cup, spoon, paper towel and hot water)
LED candles (I bought 3 flickering candles for $1.99)
black craft or hobby paint
black Sharpie
fine paint brushes
glue
pencil
scissors
orange felt pen for colouring ping pong ball
"pumpkin carving" design or template
(finger)nail hardener or clear nail polish to make eggs a bit more durable

Step 2: Hollowing Out Egg

Wash egg and poker(needle, awl etc)
Gently poke* hole in bottom, and enlarge by delicately chipping around the hole.
Poke hole in the top of the egg.
Blow (don't suck) into the smaller hole on the top of the egg until empty, forcing the egg whites and yolk out of the larger bottom hole into a bowl.
Rinse out the egg by running water into the larger hole and blowing out, repeat until water coming out looks clear.

Make sure that the bottom hole is large enough so that the light will fit.

*If you are having trouble poking through the shell, tap the top of the needle/awl gently with a spoon.

Step 3: Paint LED Candles

Before you start painting lay down some newspaper to protect your work surface.

Painting the candle base black complements the Halloween colours of the eggs.
With a fine brush apply the black paint to the base of the candle, try not to get any on the flame. You may need to apply more than one coat to make it completely opaque.

Step 4: Dying Egg

In daylight (or with the room lights on) the LED candle light does not shine through the egg, so the egg remains white. I wanted the egg to look pumpkin-like in daylight too, so I dyed the egg orange.

You can use store bought Easter egg dyes, use food colouring or try natural colouring like Easter Eggs Dyed With Onion Skins (this would look really cool, but I'm allergic to onions so I didn't try it)

Egg Dying with food colouring

In a coffee cup, mix:
20 drops of food coloring (I used 5 drops red and 15 drops yellow)
1 teaspoon of white vinegar
3/4 cup hot water.

Allow the water cool to room temperature, immerse the egg completely in the colouring, since it is hollow and floats, you will need to hold it down with a spoon. Leave it in until the desired colour is reached. Remove from cup and place on paper towel to dry.

Step 5: Design Your Pumpkin (Egg)

Plan what kind of face or design you want to use on your egg. You can draw one of your own or you can search for some online. There are a lot of pumpkin designs online, just download one you like and resize it to fit your egg. You can decorate both the front and the back of the egg too.

Step 6: Transfering the Design to Your Egg

Once you have your design, you will need to transfer it to your egg.

You can draw it free hand or you can use transfer paper if you have it. Or you can do what I did; which was to print out the design (after making sure it was the right size to fit the egg), cut it out and trace the design onto the egg.

Step 7: Paint

Colour in the design using the black paint and the sharpie. Use the sharpie for the fine detail and the craft/hobby paint for the larger areas. Use a pencil, inserted into the hole in the bottom of the egg to help you hold the egg while painting.

For one of the eggs I left most of the egg orange and did the face in black.

The egg with the ghost, I painted most of the egg black and left areas unpainted for the light to shine through, with this egg I did not bother dye the egg orange beforehand, I thought it would look okay without it.

You may require several coats to make the black completely opaque (using several coats of paint also helps make the egg harder, less fragile.)

Step 8: Using a Ping Pong Ball

If you are using a ping pong ball instead of an egg you can follow the same process as with the egg. There is just a few exceptions:

To make a hole in the ball, use a nail, and insert into ball, it is easiest when you poke the hole in the seam. With a knife carve around the hole to make it large enough to fit over the light of the LED candle. (Use caution, when using these sharp objects.)

To colour the ping pong ball orange, use an orange felt pen or highlighter.

The ping pong ball I used had a logo on it so I had to work my design around it.

Step 9: Making the Egg More Durable

The obvious problem with working with eggs is that they are quite fragile. To make these Halloween decorations more durable apply clear nail polish, nail hardener, or several coats of clear acrylic paint.

Be careful with the nail polish/hardener, I found that it can smudge the paint, so test it first. If this happens to you, you can apply it to the inside of the egg. To do this pour some inside and swirl it around to coat all of the inside of the egg.

Step 10: Finishing Up

The last step is to glue the egg/ball to the candle. Make sure that you use glue that dries clear. Dab glue around the flame of the LED candle and place egg, ensure that the egg is standing straight and not tilted and that the egg fits snuggly, with no large gaps to let light seep out. Allow to dry.
