Simple & Cheap DIY Halloween Decor: Glow In the Dark Mason Jars!

I recently stumbled onto this super simple and seriously affordable DIY decoration idea for Halloween on the addicting Pinterest: Glow in the Dark Mason Jars!

I actually thought it would be more complicated than it ended up being, but it’s not. It took less than 5 minutes to do 2 of these (one green, one purple) and every member of my boyfriend’s family loved them!

You can definitely do these yourself as a fun nightlight for your kids or for Halloween decorations that are both fun and cheap!

What You Need:

  • Various colored glow sticks
  • Mason jars (or any kind of empty glass jars with lids)
  • Sharp scissors or small wire cutters
  • Tweezers

Here’s How: 

First, you will need to purchase a few things. I had mason jars on hand already, but you can use any glass jars that you have on hand (please note, they can’t be re-purposed after this; they can only be used for this purpose or other chemical purposes due to the chemicals in it). Otherwise, if you want to purchase mason jars, they usually come at around $10 for a 12 pack at your local grocery (check the baking aisle). Then, I went to the 99 cents store and purchased a few glow sticks.

The next part is a bit tricky. You have to crack the glow sticks so they glow before you break them open so just crack them as usual. Then, cut off the top of the plastic stick with either sharp scissors or cutters ( I used sharp wire cutter things as the glow sticks I got were bulky). Once you’ve done that, you pour in the glowing liquid to your jar of choice. There will be little glass shards that fall into the jar as well. Don’t panic; it’s just how they keep the solutions separate in the glow stick. That’s the crack you hear when you typically snap a glow stick. Just use tweezers to pick the largest pieces out of the jar and toss them. Otherwise, if the pieces don’t bother you, you can leave them all in the jar. Just make sure to close your jar tightly so no one gets stabbed with glass pieces of this glow stick fluid. I left small pieces in as I plan using these jars solely as glow jars for my niece and nephews to enjoy on Halloween.

Some important things to note are – wash all things that touch the glow liquid very thoroughly with soap and water: the scissors, your hands (especially!) and the tweezers. Also, I only used single colors, but you can mix colors if you want to as you like.

So, that’s it and enjoy them!

They’re really cool looking!

I plan on keeping this one in my bathroom until the glow wears off and then adding new colors each time the glow dies to keep it going. It’s a nice way to avoid the glaring bright lights when I have to use the restroom at night; just saying!

Plus, I think it really gives off that fun, festive Halloween vibe to the house!

If you do buy a 10-12 pack of mason jars, you can do loads of things with them. Plant them strategically in rooms in your house so your house glows in fun colored light, string them up together for a fun Halloween fixture or you can put them outside your house on Halloween night.
