This invention relates to a bottom ejection type instant cooling easy-opener which can be instantly cooled down while producing a colorful gas and a whistling sound effect, wherein the easy-opener is having a circular convex (concave) seat made on the inner bottom and fixedly connected with one layer of adhesive material, a cylindrical cooler, a resilient sealing element and a metal plate; a metal injection needle having a rubber adapter connected at one end for further connection with a straw, and a whistle means set at the bottom of the circular convex (concave) seat, and wherein said metal injection needle is used to pierce through said resilient sealing element to let the instant cooling agent of the cylindrical cooler be exhausted to instantly cool down the easy-opener and to concomitantly produce a colorful gas and a whistling sound. To let the instant cooling agent be vaporized to exhaust from the stepped cylindrical cooler through the capillary holes of the metal plate to pass through the chamber of resonance of the upper and lower whistle elements so as to provide a whistle.
