Is the temperature of the water going to be in 1 degree increments? There are no specifications in the rules but I'm assuming they won't go to decimal places.

? I'm pretty sure it's tenths.... why wouldn't it be?

If you start at 77.4 predict 64.3 and it is actually 64.6, then decimals help you out.

Also tenths is standard when reading with sig figs off of a lab thermometer.

Notifying people that the question marathon does indeed still exist. Also, any thoughts on my above post about build size?

Would silica aerogel, being a strong desiccant, be a violation of General Rule #1 (safety)?

I doubt it.

BTW, Question marathon. Is it that nobody knows the answer 'cause I didn't think that the the question was to hard.

It is possible that people are not as active currently on the question marathons because it is still September. Give it time; the marathons will pick up in activity as the competitions get closer.

We are probably not getting aerogel, just because the marginal benefit isn't that high. A device using normal material probably works

In fact, remember that a device with no insulation can be good too! You can get the water, dump all the ice water in, and use a graph to predict the temperature. Heat retention score should be slightly negative, so you get out of 55 - not bad! Just score 25% higher than everyone and you medal

I will be trying to get at least some aerogel for my device. But seriously building something nearly airtight that is really small, could work.

These are 250 ml beakers, but are they allowed?

They might be. I expect that they would be looking for glass but if plastic is allowed definitely the better option as less chance of breaking yet higher insulation.

I do not know why you are buying a pack of 25 though. I think that you might be blowing a bit into your budget when the saved money (which would be over a $100) could help you buy insulation.
