Is it a boy? Is it a girl? We know it doesn`t matter as long as the baby is healthy. 
But we also know it can be awfully exciting to announce the news with a big boom, literally. The Sonic Boom Gender Reveal Kit features a 1-pound exploding rifle target along with custom-made colored chalk. Just mix up the target, place the chalk on top and shoot the target with your centerfire rifle from at least 100 yards away to trigger a colorful explosion accompanied by a satisfying boom.
Features:
Important: Make sure everyone has a good time! To ensure safety, shooters, spectators, and animals must be at least 100 yards from exploding target. Wear eye and ear protection. Shoot well away from anything flammable and don`t use it anywhere that a fire watch has been issued. Store it responsibly, away from children and animals. And ignorance is not an excuse, so check your state and local laws before purchasing or using.
