If you could invent anything in the world what would it be?

What product would you invent or make if you could? It can literally be anything. There's no right or wrong answers.

I'm sure people are wondering how I came up with this post and the truth is I was watching shark tank this morning and there are so many people who make the simplest (but brilliant) things and then over night become millionaires so I thought it would be fun to hear about things you could invent that would make your life easier or something you've always dreamed of making. Whatever the case is for you.
