In this simple instructable I am going to show you how to create a glowing sea shell that looks really nice. It is very easy to make and very cheap.
Step 1: Materials
LED- I used a 10mm RGB self cycling LED. 15-50 Cents. You can take an LED pretty much any old electronic device or buy them online. Radio shack sells them for an arm and a leg.
Coin Cell Battery- I used the CR2032. Very Common. You can get them at radio shack or online. Even Big Grocery Stores have them. They cost any where from 20 cents a piece online to close to $5 dollars at radioshack.
Electrical tape- About 5cm. You could even use duct tape.
Shell- Any shell that is big enough to fit an LED in.
