Normal life, Adventurous life

You start a lemonade stand. It's a hot and sunny day! Ha! You don't have to buy much. You have lemons in your backyard, you have water from the sink, and a freezer for ice cubes. The only thing you buy are plastic cups. You label the price, 50¢. You get some change that you already have. Then you start it! You make $200! You already bought all those plastic cups and you spent $50 on them. That means you get to spend $150!
