Tech 

I could invent a time machine! I could build a time machine to go back in time erase your past mistakes and live the past.  I would make this to help others and myself. This is going to be amazing because I feel a lot of people will want to buy this and I will make so much money and become rich. I will buy whatever I want and building this can expand science as well. an go back to the olden days. And go and see Elvis in concert. And I don't need to use any type of math or English to build something. I just need science and my hands. It will also be really fun and a memory to remember. It won't be ugly but nice and pretty. This will help the world become better because then we can go back and change our past. But I would never make this just a thought.
