Create simple circuit ornaments using wire (pipe cleaners), coin batteries, and LEDs
We really like pipe cleaners. They are soft, they come in a rainbow of colors, they bend, they are easy to work with and underneath all that soft fuzzy stuff, there are two metal wires twisted together. Those metal wires are conductive and useful for creating a simple circuit with no soldering required. Plus they look so much better than a plain ol’ wire.
Circuit = an unbroken loop of conductive material that allows electrons to flow through continuously without beginning or end.
Soldering =a low-temperature form of welding commonly used to join electrical conductors together for permanent connections
LED =a light-emitting diode is a two-lead semiconductor light source which emits light when activated.
- 2 Pipe cleaners
- 1 LED
- 1 coin battery
- Duct tape
Cut off about half an inch of the chenille from both ends of each pipe cleaner. This will expose the wire. Make sure you take off enough to allow you to twist the ends of the LED leads around the wire.
Bend your pipe cleaners into the shape as shown in the example photos or in the form of your own creation.
Look at your LED and notice that one of the metal leads is longer than the other. This is the positive (+) end. Twist the positive lead around wire at the top of one pipe cleaner. The other end of this pipe cleaner will be connected to the positive side of the coin battery.
Twist the negative (-) lead around the top of the other pipe cleaner. The other end of this pipe cleaner will be connected to the negative side of the coin battery.
Look at the coin battery and identify the positive side. It is labeled with a “+” sign. Tape the bottom wire of the pipe cleaner attached to the positive lead of the LED to the positive side of the coin battery. Next, tape the bottom wire of the pipe cleaner attached to the negative lead of the LED to the other side of the coin battery.
Your Christmas ornament topper should now be lit. If it’s not, double check your connections. Check that there is contact between the pipe cleaner wire and the battery and the LED leads. Also check that the positive LED lead is connected to the pipe cleaner that has contact with the positive side of the battery.
