1. Empty a beer can. (Soda cans or any other aluminum cans will work.)
2. Rinse can thoroughly.
3. Pull off the tab.
4. Cut the bottom off of the can with a box cutter. (Be careful not to cut yourself!)
5. Cut about 3/4 of the way around the top of the can, leaving a little bit of the top still attached. (See step 7 for a better picture of the top still attached.) Be careful not to bend the can.
6. Use scissors to cut the can in half vertically.
7. Fan the can out like in the picture below.
8. Put some tape on the bottom of the can so you can affix it your Wi-Fi router.
9. Slide your beer-can Wi-Fi extender over your router and you’re ready to enjoy better wireless reception!
