Caesar Cipher

A quick, and useful tool for basic encryption. The Caesar Cipher makes a fun game too!

- A protractor.

- A ruler.

- A large sheet of cardboard.

- A pin.

- A utility knife, or scissors.

- A cat, for testing if your cipher works.

Use your protractor, and measure out a six-inch radius for a total 12-inch diameter circle. Then, measure out a five-inch radius with a 10-inch diameter circle. Finally, cut out the two circles from the cardboard.

Take the two circles and insert the pin in the middle of the two circles, attaching them and folding the legs back. Now, mark a line in the middle, then on the other side. Keep dividing and marking until you have 32 sections.

Finally, fill in each section with A-Z. With the extra sections, add in the numbers.

Great! You're done, have fun with your Caesar Cipher!
