We made a simple machine which can pop a balloon. We used a car to pop the balloon. The simple machines were wheel and axle and inclined plane. We used cardboard to make the inclined plane. The car had the wheel and axle. The string was stick to the chair and holding the clay and the clay was holding the pin. The balloon was underneath the chair. We gathered some thousand blocks to hold the balloon in place. The car went down the inclined plane and hit the clay and the pin went to the balloon and did not pop so it failed.
