Update: RTM just talked with a representative from YAK-PAK, which is the backpack company featured in the film. The representative confirms the video was a marketing tool to help promote the new brand. Those who were featured in the video were actors, and the bombing was digitally created.
A couple of teenagers in Israel thought they would be clever and scare the police into creating a little chaotic art. The police were alerted and called out the bomb squad after the pranksters places a mysterious looking bag. When the bag was disposed of with the help of a bomb robot, it left behind some seriously colorful explosions.
