Just wanted to touch base with you and let you know how the explosive test went. I loaded two PVC pipe bombs with about 3/4 lbs. of commercial-grade C-4. The pipe bombs were placed in a travel suitcase with a pair of boots, a pair of Levi jeans and a blanket. The PowerFlare was secured to the top of the suitcase with a zip-tie and turned on. The explosion was initiated, and the suitcase, bomb, and clothes were completely destroyed. The PowerFlare was located 50 feet or so from the seat of the blast, intact and still flashing. The outer shell sustained slight discoloration from the explosion, and the loop where the zip-tie was used to secure the suitcase was torn. We were REALLY impressed!
