Dial-A-Cake

Two mirrors can multiply a single candle into a whole birthday cake's worth

Discover the relationship between the angle of two mirrors (as measured by the protractor) and the number of mirror images you see. By changing the angle of the mirrors, you can create a virtual image with the correct number of candles for your own birthday cake. As the adjacent mirrors multiply the image, more and more birthday candles can be seen.
