Need a quick toddler (or adult) costume? Here's one that can be done in about 5 minutes, using common household items.
You will need:
* a solid colored shirt
* a hat (same color as shirt)
* tape (white for dark colored shirts, black for light colored shirts)
* a pair of black pants (leggings work great!)
Step 1: Decorate Shirt
Using the tape, put a diode symbol on the front of the shirt.
Step 2: Arrange Pants
The pants represent the anode and cathode of the LED. On most LEDs the anode is longer than the cathode. To represent this, roll up one of the pant legs.
Step 3: Finish Costume
- put on hat
- turn on the flashlight to go from a "plain old" diode to a light emitting one!
