I will teach you how to stop a car with just a finger... now this might seem impossible... but it can. All you have to do... is focus your strength into the finger you want, the pointer finger is preferable. Then, you tell the person to throw the car and make it go at you. You stopped it. You know why... because it was.. TOY CAR!
No, but for real. I will teach you something that you need in your life... dabbing. Pretend like you are going to sneeze, and then with your other finger point to the opposite direction that you are going to sneeze. So you sneeze, with your sleeve, then point to the other way. That is how you dab.
