These are a fun little project that i made in less than twenty minutes.
All you need is: yellow LED, paper, watch battery, and tape.
I want to apologize for the horrible quality picture. it was the only one I could take while lighting the light bulb up. So, sorry.

Step 1: Step One

The first step is to take the piece of paper, and fold it in half. Next draw your best half light bulb shape you can, using the folded edge as the middle of the shape. Then, cut it out. It should look something like the second picture.

Step 2: Step Two

The next thing you do is trace the outline of the light bulb you just cut out. You should then have two of the same shapes, one for the front and one for the back.

Step 3: Step Three

For step three, you have to tape the one wire of the LED to the battery. You will probably have to bend the other wire to keep the LED from lighting. what you want is to be able to pinch the wires to light it up.

Step 4: Step Four

step four, is just taping the whole battery/ LED/ thing inside the paper light bulb. the way I did it was I taped the bottom shut, slid the LED/battery in then taped the outside.

I hope you enjoy this project, It's really easy and simple. please comment, and post a pic of yours if you make one.
