Well, we did last year. It doesn't make that much of a difference to be honest, since there's the hole.

One team at the Solon invite brought a screwdriver to screw closed their lid... Tape wouldn't be a bad idea, but some ES's might be weird about it. ¯\_(ツ)_/¯

And there you have it. Honestly, if well constructed it doesn't make too much of a difference; or any at all as said by cookies above.

Hey everyone,

Does the initial water temperature correspond to the temperature of the water at the very start (before entering beaker), the temperature when it first enters the beaker, or the temperature of the water in the beaker AFTER the device is fastened? Also, can water be added to the beaker while the beaker is inside the device instead of outside? Does the clock start AFTER the device is secured/fastened?

The initial water temperature is the temperature of the source bath. I would measure the temperature after the water is poured in the beaker both for your tests and for the competition. The water may be added to the beaker while it is in the device if it is easily accessible. From what I've seen, the clock starts when they give you the water.

Water starting temp is the source temp--the temperature of the water bath before putting it into the device. Water can be added to the beaker while it is inside the device, as long as there is 'sufficient access' to the beaker (thus the lid basically cant be on). The clock starts when you receive the water/it is being poured in, not after you've closed your device. Hope this helps!

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.
According to the rules, closest to 0 is best. This makes sense since a k value closer to 0 yields a lower temperature drop.
Yeah I was wrong, I forgot the rules clarification........ :cry: :cry: :cry: :cry:
I can't think of anything else to put here, so I just wrote this...

Does the beaker inside of the device have to be removable? Having aerogel surrounding the beaker makes it impossible for being able to take it out and putting it back. Will I have to work around that?

The rules say that it must be removable.
