This is a fun little thing I made that gets messages to friends and family without anyone knowing what it says. This is a fun project for kids.
Take your scissors and paper and cut two circles, on small enough to fit in side the other. Then, take the paper fastener and put one circle in the middle of the other, and stick the paper fastener in the center.Write the Alphabet on the outside of the circles. Then select a letter. Every time you want to use the code, on the inside circle, find that letter and align it with the "A" on the outside circle. Then you translate it form the outside to the inside. Enjoy!
