Explosion at school field

THIS IS NOT REAL. THIS IS A TEST of explosions, water blast, dirt charge, fire and black smoke using Adobe After Effects and was done by me. The effects (explosions, water blast, dirt charge, fire and black smoke and also the sound effects) were taken from Video Copilot's Action Essentials 2. I'm sorry if u were seriously looking forward to seeing a live explosion at a school, haha :P
