wash pumpkins in bleach water to prevent from rotting in doors. Who knew! DO NOT spray paint real pumpkins, gases build up inside and it will explode. Okay, some people have not experienced this, fine BUT, I do know it CAN happen. Now why it happens to some and not to others I do not know, therefore I would be remiss not to warn that it CAN indeed happen. So please research and take the proper precautions when painting pumpkins.
