Keep the Heat B/Thermodynamics C

Plastic was not allowed last year. It is this year.
Any comments on where he placed it.
With the required 5/8" hole, it will reduce the heat/moisture loss, not eliminate it.
I know, picky, picky.

Around the hole in the lid, on the inside, and I meant reduce, but I was tired.

I thought the rules stated that plastic was not allowed?

No they only state plastic foams as being an example of a type of prohibited foam (3.a.2). (See the FAQ that specifically addressing this line of the rules).

I just started Keep the Heat, so i barely know anything about thermodynamics. Any suggestions for websites I should go to

First, try the scioly wiki. Some really good websites I use for reference are:
http://en.wikipedia.org/wiki/Thermodynamics
http://www.physics4kids.com/files/thermo_heat.html
http://scienceworld.wolfram.com/physics ... amics.html
This website is great for learning about Heat Transfer.
http://www.wisc-online.com/Objects/View ... ?ID=sce304
But don't rely too much on the wikipedia pages as they are not 100% accurate.
If there is some math question that you have no clue how to do, just put down something random, like you actually know what you're doing. You might get some points for it.

Thanks those websites were good.

Can you use hot glue and masking tape to build the Keep the heat box? I am not sure if the hot glue counts as plastic and the tape seems to be paper backed. Also, how do they measure the dimensions? I have three rulers which are all somehow off from one another on the centimeters. Not sure which is accurate.

[sciencegeek999]

Masking Tape: I'm pretty sure yes but only if you use it as a fastener.
For the hot glue: I'm not sure because online, some websites say it is a foam.
For the dimensions, at my regionals and invite, they measured it with a yardstick.

What line in the rules makes you think you might not be able to use hot glue or masking tape? If upon re-reading the rules you think they are illegal, submit an official clarification on the soinc.org website, you will not receive any official or binding responses on this forum.

This is a fundamental issue that is part of the learning process of SO. Your ruler will always be different than ever other ruler in some way. The way to deal with this in any event where measurements are specified is to always err on the side of caution (i.e. don't make your device 20 x 20 x 20 cm, but rather 19 x 19 x 19 cm.)
