At the carnival.....Milk Bottle Pyramid
Can you beat it? Yes, but it's unlikely.
Why? This is one of the more winnable games, if you know what you're doing. Many carnivals use leaded glass for the bottom bottles, making them heavy enough to withstand getting hit with a ball (a ball that is sometimes filled with cork to make it lighter, no less).
The trick? Aim for the middle of the bottom row, and you throw as hard as you can.
