Ah, thanks for your answer. Also, would balsa wood be allowed for building? Since it's wood but it also qualifies as foam (it has air pockets).

Maybe, It is considered as a wood for bottle rockets but i dont know about keep the heat. I would use the next available lightest wood as any sane person would. Haha kinda funny balsa doesn't mean techanailly it is the lightest. Me and my friend did a trial event at nationals last year and we epicly phailed (i know i spelled fail wrong the ph makes it better
) our bird alone weighed enough to make seven compleate birds and still flew 1.9 seconds. check us out at the very end of last years national video. not with the sun chairs at the braut fest.

I'm not certain I have ever heard wood (of any type) described of as a foam before. I would submit a clarification for an official response though.

I, and wikipedia, agree:

Agree that wood is not a foam or that wood can be a foam? I think I know your response, but I think others might be confused.

Yes.
(I don't think I can be more clear than that;)

I'm not sure what to say...
But since the rules say that wood is allowed, and (I think) most wood has air pockets, I would assume that balsa wood is allowed.

What do you expect the tests to be like? Do you think that they be very heavy on equations and calculations like the Geometric Optics section of Optics or perhaps more content based?

Yes, I think that's a valid assumption. (I was just being snarky in my previous response to my brother;)

There is really no way to answer questions like these. There are hundreds of tournaments around the country, all run by different event supervisors. There isn't some secret 'event supervisor manual' that tells them how to make the tests... they see the same rules as you do. Thus it's totally dependent on the specific supervisor you have as to what the test will be like.
