Stilts are long posts you wear on your legs that make you taller. You can get lots of different types of stilts. There are ones that are very long that you have to hold onto with your hands and there are little steps for your feet. There are ones like in the picture that strap to your legs so your hands are free. And you can make your own by putting loops of string through large cans so you can hold the ends of the string, and then you stand on the cans.
