For the 2013 Builder Triathalon.
I chose the category:
"Blowing Up Buster:
Show a scientific experiment going horribly wrong; with the result being an explosion! It could be anything from modern day science, or it could be from Ancient Egypt! You decide the timeline!"
Scientist: "Welcome, Ladies and Gentleman!"
Scientist: "Today I am here to present to you my latest invention - the MC-879! With its molecular scavenging rays, it can successfully turn humans into robots!"
Scientist: "Now who would like to be the first to test the new invention?"
Male twin: "I'll go! I've always wanted to look different from my sister!"
Sister: "I'll go after him!"
Scientist: "Great! Now just sit down here while I figure out how this thing works..."
This hovercar is probably my favorite part of the entire moc. Notice the parts use for the engine, as well as the use of skis. (Sadly I forgot to take a picture of the bottom, which uses a metru leg armor piece.) The rear half is detachable to allow the minifigure to get in and out.
Robots. I tried to give them a lot of unique personality.
Classic Space Bot.
This and the following picture didn't make it into the final story, but I like the effect of the skylights on the roof which you can see nicely here.
Explosion. This scene was pretty fragile; it also took up a lot of trans-clear pieces.
