Dentist chair with working light. You can turn the light on and off with a switch that is mounted to the back of the chair!! 100% my original idea and design. This may be my most favorite cake order ever. The customer doesn't know anything about the working light. It is my extra surprise idea for them. I can't wait to see the reaction tomorrow when I deliver the cake and turn the light on!! I LOVE my job!!! Rebecca's Creative Cakes - Owner - Rebecca Avans
