Students were given precise instructions on how to proceed:
Step 1: Plan out your under-car duct with cardboard, designing it to capture as much free air as possible.
Step 2: Use your cardboard pieces as a stencil for the metal pieces, tracing each piece with your sharpie. (I think this is how NASA develops prototypes for space shuttles. Or did, before they stopped making them.)
Step 3: Test out your cardboard design under the car.
Step 4: Cut with snips, bend with pliers, drill 1/8" holes (for rivets), and rivet the metal model to match your cardboard design.
Step 5: Test fit your metal prototype under the car.
Seems pretty straightforward, right? Let's take a look at one of slides included in the presentation.... (Warning: nerd alert)
No, wait, that nerd alert warning was premature. Here's the real deal.
Safety first. (See? I'm not just hyper about bike helmets.) Anyway, here's the fun stuff: a clip of the first group of students testing their cardboard design... on the race car.
Next up, the middle school girls try out their design....
