Hand made Rocket,,, The ignition burns through and ignites the kick charge... blowing off the "Legs Pantyhose Egg" Nose Cone (chrome silver line above blast), followed by a small near nuclear mushroom shaped flame blast. and all the fireworks.

Dude obviously likes fire... He stares at the explosion, and doesn't turn his head or move until the rocket begins to launch...at the end of the video, The flames from the rocket engines are as big as he is.
