The world is becoming more and more convenient. If you don’t have enough time to go to a store, you can go shopping online. You can find almost everything you need on the Internet these days. In Japan, it usually only takes one or two days for your purchase to arrive in the mail. It can take much longer in North America, so one big online shopping company is developing helicopter drones to deliver small packages to your door. According to the company, these helicopters will bring your purchase to your house in 30 minutes! Doesn’t it sound like science fiction? (by Professor Douglas Jarrell)
