9. Stick down two twigs at the top for the antenna. These do not go through the holes. Leave a clear gap between them for your LED light to fit through.
How to Make a Glow-worm Lantern
Glow-worms and fireflies have to be among the most magical creatures around. Living creatures that glow; is there anything stranger or more wonderful?
When we discovered there is a native British (or rather, European) glow-worm, we were inspired to make a lantern version, that shines just like the real thing.
Quick and easy to do, they are a great way to inspire children to learn about real glow-worms and the magic of bioluminescence. Read on to find out how to make them!

Stars in the grass
It was while camping in Dorset one summer that I first learned about our native glow-worms. Until then, I’d always assumed that fireflies and other bugs that glowed were the kind of exotic wonder only found overseas.
But as we sat round our campfire one evening, I caught a glimpse of green light in the long grass of the meadow. Intrigued, we discovered that it was a glow-worm. While their numbers (like many insects) are in decline, they can still be widely found all over the UK, including right on our own doorstep here in Buckinghamshire.
Motivated by this sighting, the children and I decided to learn more, and were inspired by what we found to make these fun lanterns.
If you’d also like to discover all about the glow-worm, you can read all about them on this separate page, where I’ve also listed our favourite external resources. There’s lots of fun stuff for the kids as well as links to more detailed information, including how to find them in the wild.
How to make a glow-worm lantern
Making a glow-worm lantern is a great way to to get kids interested in these amazing insects, and the end result is absolutely beautiful. They are simple to make, although very young children will need help with the fiddly bits.
I’ve also got a separate template for a firefly lantern instead, in case you live in a place where they are your native glow-bugs. It’s put together exactly the same way, but it also has wings for you to cut out and stick on the back!

Materials needed
You will also need to download my glow-worm lantern template or firefly lantern template to print out. It’s a very simple design, so if you don’t have a printer, you should be able to copy it freehand instead.
Instructions
Print & cut the glow-worm lantern template
Start by printing or copying the glow-worm template or firefly lantern template onto a piece of tracing paper. You could also use regular plain white printer paper – the light should still shine through, though it obviously won’t be quite as translucent.
If you want to give the kids more practice of their fine motor skills, you could get them to trace the template from the print-out instead. They could trace the template onto coloured tissue paper if making their glow-worm lanterns this way.
We like our glow-worm lanterns plain, but they also look great with colour and patterns. If your children want to colour theirs in, then do that now.
Cut out the glow-worm shape and fold in half along the dotted line, making the front and back of your lantern.
Punch out holes
Using a hole punch, sharp pencil or scissors, cut out the three holes on the dotted line. These holes are for you to poke twigs into later, to make the legs on the folded side of your glow-worm.
Also cut out the four holes at the top. With the glow-worm folded in half, these holes line up so you only need to punch twice. These top holes are for threading string through at the end, to make a handle for your glow-worm lantern.
If your tracing paper is very thin, you might want to reinforce these parts by sticking down a strip of clear tape on the inside of this area, before you make the holes.
Add legs and antenna
To make the legs, insert a twig through each of the three holes along the fold line. Use sticky tape on the inside, to hold the legs in place.
Position three more twigs opposite these, on the open edge, so that you have legs on both sides of your bug. Then tape these into place too.
Now add two last twigs at the top for the antenna. With these top twigs, be careful to not block the holes and leave a clear gap between them, so that your LED light will fit through.
Glow-worms are insects, so they have six legs and antenna. Take a look at a picture of a real one so that you have an idea of what size twigs to use.
Make a frame for the inside
Cut three thin rings from your cardboard tube. About half a centimetre wide is fine.
Cut six strips of double-sided sticky tape, each long enough to go half-way around the cardboard rings. Then attach these pieces of tape all the way round the outside of each ring, two strips of tape per ring.
Next, place the rings horizontally on the inside of your glow worm, lined up at a 90° angle to the dotted fold line. Positioning them on the horizontal lines makes them less noticeable when the lantern is finished.
Now remove the backing from the sticky tape on one side of each ring only and stick down on the right-hand side of your glow worm. Leave the paper backing on the rest of the tape for now, so that you don’t accidentally stick the two halves together before you are ready.
Finishing your glow-worm lantern
On the inside-right side of your glow-worm lantern, stick double-sided tape around the bottom and outer edge, including the gaps between each ring.
Be sure to leave the top edge (where the antenna are) clear of tape. Because you’ll need an open gap big enough for your LED to fit through later.
Remove the backing paper from all of the sticky tape (including the tape on the cardboard rings).
Fold the open side of the glow worm cut-out carefully over the rings, sticking it down into place and sealing the edges.
Make sure the bottom, where your light will sit, has no open gaps for the LED to fall through.
(For a simpler method to use with younger children, just get them to stick their glow worm lanterns together with clear tape on the outside. This makes it a lot easier for them to do by themselves)
Firefly wings
If you’re making a firefly instead of a glow worm, now’s the time to cut out and stick on the wings. There is a picture on the template to help you position them.
Fireflies (like male glow-worms and other beetles) have two sets of wings. The top set are actually hard protective cases, called elytra (a fact that will delight any young Minecraft fans). The bottom set are the flight wings.
Make it glow!
Turn on your glow-worm LED light and drop it down into the bottom of your lantern, shaking it into place if necessary.
We used bullet-shaped green LEDs (often used for balloons), that have replaceable batteries and an on-off switch. Some similar LEDs flash or fade on and off, like a firefly. You can also get them in yellow, white, blue, red, or even multicoloured.
These ones glow steadily, just like a real glow-worm, and the green is not a bad match either, so we thought they were perfect.
Handles to hang on with
To finish off, thread string through the holes at the top of your glow worm. These will close up the top of your lantern and form a handle. This will also allow you to tie your glow worm to a long stick for carrying.
When you want to turn off your glow worm, just open up the string and shake out the light.
Finished! A glow-worm lantern
These glow-worm lanterns are fun to make, and look fabulous when finished. We made ours in the summer, when real glow-worms were lighting up the countryside, but I think any kind of lantern really comes into its own in the darker days of autumn and winter.
Because they are relatively small and very light, these glow-worm lanterns are great for kids to carry around, too. The twig legs and antenna are a bit vunerable though, and won’t take a lot of knocks or swinging around. So you might want to make ‘carrying’ versions without these!

Step 1: Assemble the Circuit
Connect the circuit shown in the photo.
The longer terminal of the LED, the anode is connected to the resistor, the positive terminal side. The shorter terminal, the cathode is connected to negative terminal of the battery.
In the PSpice software circuit drawing shown the three diodes are used to model one LED. This software does not have a LED component drawing in it. Thus diodes are used instead.

Step 2: Bend the LED Legs
Bend the legs of the LED to make stronger connection that cannot be pulled apart easily. Note that one of 680 ohm resistor terminals where already bend in the previous photo.

Make the glow worm from plasticine, insert the circuit and you are done.
In the other photos you can see the glow worm LED changing colour from red to green and then to blue before repeating the cycle.
