Describe the best and most creative idea you have ever had?

Socks that don't get wet no matter what

Personally one of my best Ideas was to put small windshield wipers on glasses. They may cost a bit more but they are convenient for the owner. My sister actually has glasses and told me the idea was smart because when it's foggy outside you can turn the windshield wipers on when its snowing you can turn them on. They are also removable so you can choose if you want to wear them or not.
