I like to listen to music or "Rakugo" Japanese traditional comic story telling in a hot tab.
I used to put my iPod into a plastic bag and secure the top with Sellotape or rubber band not to the iPod get wet, but it is kind of a bother and messy to take out the iPod out of the bag after I get out the bath.
So this idea came to me when I saw a small - almost the size of iPod - plastic zipper bag at a drugstore.
This is a extremely simple to make drip-proof iPod bag.

What you need is:

iPod
a small plastic zipper bag
a disposable stereo headphone (drip-proof one is perfect)
hot glue

Step 1: Put IPod Into the Bag

Put your iPod into the zipper bag HEAD FIRST.

Step 2: Insert Plug

Hold the bag firmly pressing the iPod to the inside of the bottom of bag.
Insert the plug of headphone into the jack punching a hole on the bag.

Step 3: Secure the Gap

Using a hotglue gun, fill the gap between the hole on the bag and the plug not the water leaks in.

Step 4: Conratulations!

This is it. Easy, isn't it?
Open the zip and pull out iPod carefully.
You can use it repeatedly until the bag will be torn.

Never ever drop it in the hot tab.
It's all just a drip-proof.
Thanks!
