Step 1: Here's what you need to make a glow stick!
- 9-volt battery
- Battery snap cap
- A string of ornamental lights (that can be destroyed)
- Duct tape
- Wire strippers
Step 2: Cut off the electric plug that has the two prongs
- NOTE: MAKE SURE THE LIGHTS ARE NOT PLUGGED IN WHEN DOING THIS.
- Cut as close to the plug as you can.
Step 3: Cut off four bulbs
- Cut the wire as close to the fifth bulb as possible so you have about three inches of wire at each end of the string.
Step 4: Separate the wires
- Hold the first bulb. Find the plastic-coated wire it is connected to.
- Untwist that wire from the others. You’ll end up with one wire with four bulbs attached.
Step 5: Strip the ends of the wire
- Strip off the plastic coating so you have about ¾ of an inch of exposed metal wire at each end.
- Be careful not to press the wire strippers so hard that you cut through the metal wire.
Step 6: Pop a snap cap onto the 9-volt battery
- Both snap cap wires should have about ½ inch of exposed metal wire at the end. Strip them if necessary.
Step 7: Make a connection
- Twist together one metal wire from the light string and one of the snap cap’s metal wires.
- Use tape to make a solid connection.
Step 8: Complete the circuit
- Complete the circuit by attaching the other two exposed wires as in Step 7.
Step 9: Test the circuit
- Does your glow stick light up? If not, press on the connections inside the tape. Also make sure you have a fresh battery.
Step 11: Did you know?
- A circuit is a path along which electricity can travel. When you connect the wires from the lights to the wires on the snap cap, you’ve made a circuit. When all parts of the circuit are connected, electricity flows from the battery to the lights and back to the battery, making your glow stick glow!
