DESC: Bomb bags. A fun gag gift for years and years. Squeeze the bag so the two chemicals inside mix and watch the bag expand until it finally bursts with a loud BANG! Although the chemicals are perfectly safe because of the explosive nature of this item we don't recommend this for children under 9. Packed in display boxes of 6 dozen (72) pieces. Priced by the 1 dozen but please order in increments of 1 dispaly box (6 dozen pieces). DO NOT hold the bag close to any person/animal once activated.
