Make a pocket sized glowing magic charm using an LED, coin cell battery, tape, and craft materials to practice simple circuits and creativity.



Step-by-step guide to make a pocket-sized glowing magic charm
Step 1
Find a clean flat workspace and ask an adult to stay nearby.
Step 2
Look at your LED and find the longer leg (positive) and the shorter leg (negative).
Step 3
Cut a small circle or rectangle from paper or felt to make a pocket-sized charm base about the size of the battery.
Step 4
Place the coin cell battery on the charm base with the + sign facing up.
Step 5
Lay the LED on the battery so the longer leg rests on the + top and the shorter leg lines up along the battery's edge.
Step 6
Stick a small piece of clear tape over the longer leg to hold it firmly on the + side of the battery.
Step 7
Cut a narrow strip of paper and fold it in half to make a little flap that will act as a switch.
Step 8
Slide the folded flap under the shorter LED leg so the flap can press the leg against the battery edge when you fold it down.
Step 9
Tape the hinge edge of the flap to the charm base so the flap can open and close easily.
Step 10
Close the flap to test that the LED lights and open it to turn the light off.
Step 11
Decorate the charm base with colouring materials glue or small craft pieces to make your magic design.
Step 12
Add a small loop of tape or a tiny folded tab so you can tuck the charm into a pocket or hang it on a string.
Step 13
Share a photo and a short description of your finished pocket-sized glowing magic charm on DIY.org

Help!?
What can we use if we can't find the coin cell battery, felt charm base, or clear tape?
Use a same-voltage 3V button cell like a CR2032 in place of the coin cell battery, cardstock or a small scrap of cardboard instead of felt for the charm base from step 3, and clear packing tape or a transparent adhesive strip where step 5 calls for clear tape to hold the LED leg.
My LED doesn't light when I close the flap—what should I check?
Check that the + sign on the coin cell is facing up, the LED's longer leg is taped firmly to the + top as in step 5–6, and the folded paper flap is correctly slid under and pressing the shorter leg against the battery edge per steps 7–9.
How can I adapt this activity for younger or older kids?
For younger children have an adult pre-cut the charm base, place the battery, and tape the LED leg so the child can decorate and practice opening and closing the flap, while older kids can follow all steps and then add extra LEDs, stronger hinges, or a punched hole for a keyring.
How can we make the charm more interesting, brighter, or easier to carry?
Try adding a small paper cone or frosted bead over the LED for a softer, brighter glow, glue on sequins or translucent craft pieces during step 11 for personalization, and attach a tiny keyring through a folded tab as described in step 12 to hang it from a string.

Facts about basic electronics for kids
✂️ You can make safe, low-cost circuits using copper tape, aluminum foil, or pencil graphite instead of soldering.
🔋 A common coin cell like a CR2032 is about 20 mm across and can power a small LED for many hours.
🧩 For your charm to glow the battery, LED, and connectors must form a complete loop — break it and the light goes out!
💡 LEDs were first shown as visible light sources in 1962 and today they’re tiny, bright, and energy-efficient!
🎨 Tiny glowing charms mix art and science — simple paper-circuit projects are great for kids (with adult help) to learn STEAM.
