iPhones, iPads, Androids, Kindles, and many other smartphones and tablets have a capacitive touch screen, which needs an electrical conductor (like the human body) to register where contact is made. Nintendo DS, The 3Ds, the Nook, and some other phones and e-readers use resistive or infrared touch screens, which only require pressure to register contact. You can use just about anything as a makeshift stylus–just be careful not to scratch the screen.
A cheap, plastic pen works best, as long as you can easily pull off the plastic tip and remove the ink. A slightly see-through pen can make it easier for you to see what you are doing.
You should be able to pull the tip off with just your hand. If you have difficulty, try using a pair of needle-nose pliers.
If you don’t have a pencil, you can substitute a pen, a chopstick, a dowel–anything pen-shaped. Pencils or other wooden objects work best, however, as you may want to cut your stylus to have an angled tip.
The stylus will work without this step, but you will have to hold it straight up and down. This will make it more comfortable to hold. Always be careful when handling a knife–remember to cut away from your body. Never pull the knife toward yourself.
If you are using a pen, keep the cap on the pen when you wrap it.
If your tip is not flat, your stylus may not work.
Try not to use an electric pencil sharpener–it may break.
Sand any rough edges of the chopstick as well so you don’t get splinters. [8] X Research source
Remember: this stylus will not work on an iPhone, Android, Kindle Fire, or other device with a capacitive screen.
