A prototype is like a rough draft or a model of something new that you want to create. It's an early version or sample built to test an idea or see how things might work. Imagine you're designing a new car, and before building the final version, you make a prototype with cardboard and tape to see if it's the right size and shape. In the world of design and invention, a prototype serves as a test run to figure out what works and what needs improvement. It's a bit like making a practice cake to perfect the recipe before baking the real one. Prototypes help creators and inventors avoid costly mistakes and refine their ideas before making the final product.
