Below is a fun little project I worked on last week in some spare time. Follow the instructions displayed at the bottom of the video carefully. With any luck, I might be able to read your mind right through your computer screen!
In case you can’t figure out how it works, watch the video again and you’ll be sure to figure it out ;). If you’d like detailed steps on how to perform this mini miracle for your friends, be sure to watch part 2 of this video (linked at the end.)
