Friends! How is the thing happening? Did you try the toy planes we make here? Today I am going to show another simple toy plane design that you can make very easily but have a great fun. Today we make Balloon Plane. You may wonder what this balloon plane is. This is again a simple plane uses the rubber balloon to generate throttle power. You know that once you fill the rubber balloon with air, inside the balloon air in under pressure. Once you release this air you can generate pressurized air flow from balloon’s mouth. This air flow can be used to push your plane forward very easily. Now you can imagine what I am going to make here. Even though this is a simple plane design if you control the air flow correctly you will be able to fly your plane considerable long air time. It all depends on the balloon size, straw size and length. You need to fine tune these parameters to get optimum flying time. That means if balloon is large we can expect long flying time. If straw size is small again we can expect long flying time, but if it too small forward thrust might not enough and falling down your plane. That is why you need to adjust the balloon size and straw size to make a nice plane.
