Halloween Decor: How to Make Glowing Specimen Jars

Brighten your Halloween decorations with these neon-green, glowing jars that look like they came straight out of a mad scientist's laboratory.

Florescent-green, battery-operated tea-light candles are the secret to getting these spooky laboratory potions to glow. The remote-controlled lights are waterproof and cost about $25 for a pack of 10. After Halloween, you can change the color of the tea lights and use them for other holidays or decorating projects. Our free specimen jar labels also make this project easy and inexpensive.

Tools and Materials:

1. Prep + Fill the Jars

Clean and completely remove the labels from the jars and lids. Fill the jars almost to the top with distilled water. Distilled water will last about a month and not get moldy. Add 2 to 3 drops of neon-green paint into each bottle and stir.

2. Add Bugs

Insert toy plastic bugs into each jar. One large bug works better than a few smaller ones.

3. Glue On Lights

Remote-controlled, waterproof LED lights will give the jars an eerie glow. Use hot glue to attach the lights to the underside of the lids. Screw the lids onto the jars and test that they work. Be sure the water level touches the lights, or you’ll get a reflection instead of a glow.

4. Print + Age the Labels

Print the template for the labels onto shipping labels. To make the labels look old and gnarly, use a straw to drip coffee down the label while holding it upright. Allow this to dry completely. Rip the edges of the labels for a worn look. Stick the labels to the jars and place them.

5. Light Up the Jars

Turn on the lights in each jar and watch them glow.
