This little demonstration was created for a 20 min lighting talk at the 1st Israeli Blender User Group (BUG) meeting.
It utilizes the explode modifier along with particle systems, the cycles render engine (exploding text) and internal engine (exploding watermelon scenes).
Two models who were made by others were used here:
Watermelon By SSIMPOSSIBLE
A-1 Turret By HJMEDIASTUDIOS
