This is an Instructable telling how to make a stylus for your capacitive touchscreen device. This worked quiet well on my iPod touch 5th generation. This is made out of household materials, so you wont have have to go looking for stuff in the market, like you need to in other Instructables that tell how to make a stylus.
I am not responsible if this causes any harm to your device

A straw, cotton, foil, 2 elastics, tape (optional)
