So in that case can I use cotton wool, or any similar fibrous organic materials?

As long as it is organic fibers or granular, you can use it. For mine, I am using 100% wool and cotton. If you use wool, make sure it is 100%.

The latest FAQ banning corn starch packing peanuts for the reason of being a foam appears to prohibit any form of foam, regardless of granular form or organic composition.

There goes my brilliant idea....

Hello,

I was wondering if organic foams are permitted for this event, the rules say that foams are not permitted, but they only mention synthetic examples, Styrofoam, polyurethane foam etc...

Can the device be made from natural polymers, aka proteins, which can be manipulated to form both fibers and foams? I am asking this because naturally derived foams do not fit in either the prohibited nor the permitted materials.

At the very least, can a protein based binder be used to make cellulose based foams?

I'm curious. the exact wording in the rules is that you are prohibited from using 'any type of foam'. It doesn't say 'any type of inorganic foam'. How could we be more clear in the future?

Perhaps you could increase clarity by specifically excluding foams in the materials allowed, as opposed to including it as an example of a prohibited material.

Hunh? We have a list of materials allowed, and a list of example of prohibited materials. Are you suggesting putting foams in the allowed list?

[Schrodingerscat]

I was initially suggesting rewording it slightly to specifically say no form of foam is allowed, rather than the current wording that any type of foam is an example of a prohibitted material. However, including the restrictions as a list of examples does provide the benefit of indicating it is not a fully exhaustive list.

Are you allowed to spray paint your device?

Are you allowed to spray paint your device?

This question has been discussed several times previously on this thread. The general consensus is that it would give no benefit other than contributing to the insulative properties, and thus violating the rules.

I am averaging 18 points is that good compared to you guys?

Are we allowed to use store-bought clay in our device? Or does it have to be organic?
