A Sticker You Wear Could Let You Feel Video Game Worlds!

Scientists created a super thin patch that works like a Band-Aid and can make your skin feel different textures in virtual reality [a computer-made world]. Tiny dots move really fast across the patch to trick your brain into thinking you're touching real things like silk, leather, or bumpy surfaces—even though you're just wearing a sticker! Imagine playing a video game and actually feeling what you're touching!
