I just wanted see some of the sketches for this one:
high-impact quantum dairy creamer
when placed into a cheap 2-day old styrofoam cup of gas station coffee, an intense reaction
spawns a dreaded supersonic cow which gains speed and mass as it is hurled upward into space.
After exceeding the speed of light and traveling back in time, it eventually plummets back through the atmosphere in a fiery blaze
and collides with a random ancestor of the unfortunate coffee drinker, thus eradicating itself, the event, and the poor java-chugging victim in the future.
Stealth = Yes. The target doesn't see the cow coming as it takes the long way around.
Projectile = Yes. That's one very fast, giant flaming hamburger.
Ammo = It's a one shot termination. See above.
Model = No. Models. Min. ingredients = target, gas station, cup, coffee, creamer, cow, earth + atmosphere, some stars, Einstein holding semi-transparent clock and shaking his head,
time-flash, motion trails, meteor-like blaze, ancestor with dazed look-up animation, crater, optional barbecue cult members
I'm sure your team could crank out a reasonable simulation of high-impact quantum dairy creamer in 1.7 days.
