Staying Close to Home for Vacation
Planning a vacation is fun! You pack your clothes. You pack your games. You plan your food. Your parents plan, too. They plan a budget. That means they decide how much money they want to spend. One part of a vacation budget has gone up a lot: the price of gasoline.
Gas prices have been going up, up, up! This means that some families are staying closer to home on their vacations. All kinds of transportation use gas-powered engines. Car engines use gas. Airplane engines use gas, too.
Nikolaus Otto invented the engine. It is used in many vehicles. It is called the internal combustion engine. He invented it at the end of the nineteenth century. His engine had a piston chamber in it. Fuel burned in the chamber. Cars could use this engine. Thirsty cars could then drink gasoline.
