I’ve been making and using duct tape wallets for years now and I have to say they work just as good as, if not better than, a regular wallet. Most people do not realize how easy and fun it is to make one, so this guide will help you make your own.
In recent years, researchers have developed technology that allows people to control computers and wheelchairs with their brain waves.
