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:
a small plastic zipper bag
a disposable stereo headphone (drip-proof one is perfect)
Step 2: Insert plug
Insert the plug of headphone into the jack punching a hole on the bag.
Step 3: Secure the gap
Step 4: Conratulations!
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.
