MIAMI, FL – A dad started a sibling battle in the back seat of his Tesla to see if either his son or daughter could drink water without spilling. As soon as he hit the gas, water spilled all over their faces, clothes and the seat. He decided to give them one more chance and offered twenty dollars to whomever had more water left in their cup. Once again, the water went flying everywhere from the G-force of the acceleration. In the end, his daughter won the money.
