Refillable air horn lets you be loud and obnoxious over and over again

The problem with air horns is that they run out of air quickly, making it difficult for you to sustain an eardrum-destroying level of horn blasting for very long. With this EcoBlast, you can keep refilling your air horn with a pump as much as you want, getting you back into the loud-noise-making action as soon as possible. All this for only $30! How can you say no?
