Errr, I'm pretty sure that any ES would interpret the rules in the reasonable manner; that's a bit extreme logic there.

Also, k values are negative. The best k values are those that are closest to zero. Something like -0.0001 would easily win, and get 20 points.

Wouldn't a k value of -0.001 be better than -0.0001 because -0.001 is lower? And thus, a (hypothetical) k value of -1 would be even better, because it's even lower. K value closest to 0 isn't best, lowest k value is best.
I can't think of anything else to put here, so I just wrote this...

According to the rules, closest to 0 is best. This makes sense since a k value closer to 0 yields a lower temperature drop.

if -1 was the best k value i might as well bring a chunk of metal as my box...

Is stopping convection really going to make a difference in my k-value? I am thinking of adding a bunch of foam bits and pieces in between layers of foam and also around my beaker where there are gaps in insulation.

No, not really. Just make sure there's as little free space in your box as possible to increase thickness instead.

Thanks. By the way, is the foam color that I use going to change much? Right now, I have white-colored foam, so it doesn't absorb as much radiation from the surroundings. Is this more ideal than darker-colored foam?

It doesn't really matter that much. If you're going to talk about radiation though, use reflective foil/other like material to reflect radiation. Line the inside.

Are we allowed to tape down the lid of our box after putting the beaker in?
