I made a Cup with a heated handle that changes colors. This is better then the original normal cup because it can make drinking something more fun. I came up with idea on weekend when i was drinking chocolate milk and I thought to myself "Hey I wonder if I can make drinking something more fun" . I thought and thought for a long time and finally came up with the idea to have a rainbow cup that had a heated handle. The thing that I like most is probably the rainbow. I say this because i came up with the idea of a heated handle from my dad saying he hated when the cup was warm but the handle was not . The rainbow was a bonus because I thought the color was blain. In the writing on the side I said that since you have to charge the battery it will not be dishwasher safe, but you can still wash it by hand
