Using this air stacker is super easy. First, place the rocket ball in the base. Then, insert a clear tube on top of the base. After that, turn on the fan. As the fan starts working, you can stack additional tubes one by one. You'll be amazed to see the ball flying up to the top of the stack. For safety, make sure the fan is placed on a stable surface. Keep small parts away from children to avoid choking hazards. To maintain the product, clean the tubes and the base regularly with a soft cloth. When not in use, store it in a dry place to prevent damage.
