Picture of LED Sponge Lamp
In this Instructable, I am going to show you how to make a unique sponge LED lamp. For this instructable you will only need some basic Radio Shack items and a dryed sponge that cost about 2 dollars. I hope you enjoy this Instructable and I would appreciate it if you vote for me in the LED Contest.

Step 1: Items You will need....

For this Instructable you will need:
1. dried coral sponge
2. scissors
3. Cardboard cutter
3. bright LED (9 volt)
4. 9 volt Battery
5. Wires
6. small Switch
Actually pretty cool.
But wow, 9V LED?! That's crazy.
I would most likely use a RGB LED, and a resistor (never forget them!), that would be really cool.
Nice job, still pretty cool.

Hm... where did you find a 9V LED? White LEDs are typically somewhere between 3 and 4.5V.

Even if you do have a real 9V LED, you would still want to put a small resistor in series with it. Otherwise, next time you clip on a fresh 9+V battery, your LED may be toast...

By the way, this "sponge" you use is called a loofa (or luffa), and is not actually a sponge but the fibrous inner part of a type of gourd.

As you can tell in step 4, a loofa typically has 3-4 compartments. For a more advanced version, I think it might look nice to have a slow color changing RGB led in each compartment.

Nice idea, it looks like a very soft light, and the texture of the loofa comes through nicely.
