Is fiberglass allowed for heat insulation?

Not quite. The policy on built devices is that someone on your team of 15 had to build it and that anyone can operate it (meaning compete with it). If anyone who's still with your team--even if they are not in Thermodynamics--worked on your device, you're clear.

Check out the general rules (#7 in particular): http://soinc.org/ethics_rules

Part of my device extends below the below, it's less than 2.5 cm ABOVE the lip of the beaker.
however if you account the portion below the beaker than it would be out of specs. What are you're thoughts? Should I send in a rule clarification for this? Thanks in advance

Depends on what kind of fiberglass. If its being sold in any way to provide insulation, then no, as it's a commercial insulator.

Thanks for the clarification... the situation I was talking about was a member of my team who was on Thermo last year built a specific part to his box which I wanted to use as part of my box this year. Thanks!!!

This question is actually re: the Metric Mastery event, but someone knowledgeable about this one may be able to help me.

This event bothers me for several reasons. It's not just the density thing. How about temperature? How can a supervisor hold something at constant temperature (scoring correctly requires this) for the duration of the event without an expensive temperature-regulated water bath normally found in a laboratory? I'm hesitant to asssume that even water won't have fluctuations in temperature over a few hours. It would equilibrate at room temperature (within what margin?), so I suppose an 'actual' temperature could be recorded before the event is ran or something (that's not good practice). Is that the best that can be done? That is a bit lame considering estimating room temperature is one of the simplest possible tasks.

Is modeling clay considered a foam? I know it says clay, but it is a little different from clay right?

I'd think it will really depend on what kind of modeling clay you are using. If its real clay, or has very similar properties and consistency, then I think it would be allowed. However I know there are many types of fake clay, that are not really like clay at all but more like a plastic based dense foam, which would almost certainly not be allowed.

Thanks, I guess I'll just steer clear of it to be safe! I just had a major panic attack when I thought my duct tape was electrical tape , thankfully that wasn't true, but I don't want another scenario like that!

Is anybody else noticing a decline in efficiency of their boxes from last year to this year (assuming you did the event last year) due to the smaller size restrictions. I know the size restrictions posed a couple problems for me but I got around them but had a to sacrifice a couple of degrees from last year.
