Firefly Lanterns Powered By Bioluminescence: Made From Glass Juice Bottles and Salvaged Wire

Catching fireflies is the quintessential children’s summer evening activity. Every new generation is captivated by these magical blinking moving lights and instinctively wants to know the source.
Make one today or If you are having a summer party that will continue after dark, make a bunch for your young guests.

How to make a firefly lantern:

Save your empty glass juice bottles. Take off the label and clean it.
Use scrap electrical wire to make the handle for your lantern; you will need a piece about 30 inches long. We had some pieces left over from an addition to our house. You might try calling an electrician in your area; maybe they could give you some scraps that would otherwise just go in the dumpster. How-to make the handle:

1. Start on one side of the lamp (point A), go half way around (point B).
2. At point B, bend the wire up for the handle. After you form the loop for the handle, you should end up on the other side of the bottle (point A; where you started).
3. At point A, bend the wire end around the handle loop to secure it.
4. The wire will continue around the neck of the bottle and attach at point B. Use wire cutters to trim off extra wire.

It is a lot easier done than said.

You will want to cover the top of the bottle to prevent the fireflies from prematurely escaping. You could put holes in the cap and use that. Or trace a large cup on a scrap piece of fabric and cut out with pinking shears if you have them. That circle of fabric is held in place with an elastic band. I have a little stash of elastic bands that came off of vegetables or other packaging. You will find a second use for them in projects like this and many others.

Did you know that there are thousands of different species of fireflies? Fireflies blink to attract a mate but some mimic the blinking pattern of a different species of firefly in order to lure them near so they can eat them. Yikes!

Did you know that Fireflies produce light via a chemical reaction?
