Thank you,your very nice comment hits a point of frustration for me. I am not sure how to go about realizing the potential in the things I create.

Air-flow is the main concern when building such a thing. When there is a lack of air-flow, we breath the same air multiple times, moistrurizing it with every breath and reducing the oxygen it contains. I think that is the mechanism you refere to. This is addressed, by making the volume of air inside the hood as small as possibe, but at least so small, that it can only fill the lungs of the wearer so far, that the rest of the lung-volume is enough to provide enough oxygen to the wearer. This should make it save, even with very bad air flow. But the deep breaths that can require get uncomfortable rather quickly. I have to reduce the volume more.It is further addressed by making sure the hood doesn't collapse when the wearer breathes in, but instead fresh air from outside is sucked into the …

I have to reduce the volume more.It is further addressed by making sure the hood doesn't collapse when the wearer breathes in, but instead fresh air from outside is sucked into the hood, mixing with the air, that is already there.There is an accidental feature, that helps when wearing it over a longer times and is the reason, that I am not sure the two aboth mentioned work as they should. I can pump fresh air into the hood, by nodding my head. I think this also reduces how much water condenses inside. Shallow breaths with an open mouth increas condensation probably in part, because it leads to more moisture beeing transported from the lungs, but also because less air is exchanged.The direction of air flow seems to be a factor. Breathing out through the nose leads to less condensation and a more pleasant climate inside, maybe because the air is directe down and out.The situation, when condensation becomes so strong, that it itself is a problem, is going outside, when not air-flow, but temperature becomes the main driver. This had me distacted from the situations, where condensaton is a good indicator of air-flow. I will keep this in mind.Thank you

Yes, I think that would be cool. The mask is weak to tearing. I had it folded in my pocket, in a pack of tissues. It got stuck to the sticky part of the tissue pack and teared along the nose part. So enhancing durability has to take that into account.

Yes, as I learned through your comment, I meant space blanket and will replace the word in the instructable, because the connection to space flight makes the material way cooler to me. The mask can either stick with sweat or face cream, but I didn't want to mention the former, because it seemed distasteful, so heat shouldn't be a problem. I was astonished to find out, that one can see through space blanket and am surprised, that it works with a chips bag as well. Very cool, I will try that as well. What do you think about sharing your version via the "I made it"-Button, or make an entirely new instructable. Chips bags as material open entirely new options for how one can make this type of mask look (different from glossy gold) and how they can be used. With out fear to blind eve…

With out fear to blind every one around with reflections for example, so that would be pretty cool.

:D thank you for the super nice and encouraging comments. For usage by people with problems holding things, I see the difficulty that the gauntle of gripping makes opening one's hand rather difficult, but it's an interesting direction. You bought me to some ideas there :)

:) I think that would be a greate way to use it. In that case you might want to skip the water proofing spray, that stuff seems quite flamable.

I agree. Might be because I have never seen an actual t-rex, but in my mind it's basically a big chicken. I wish I would think the other way around. Regarding chicken as small t-rexes would be nice.

wow, that guy is amazing :D , I'm jealous of his dedication.

why do you think so?

Wow, that is incredebly awesome :D thank you so much for sharing

Thanks, I'm happy you see some use in it. How would this replace a vacuum glovebox?

Ye, sport gloves would probably also be better for continued use and stability. The wrist part is uncomfortable, because it is pushed against the hand by the drawstings, if the sporting gloves would avoid or lesssen that, then they would make it much more comfortable.I think this can be improved a lot, by simply using the right parts and materials. I didn't see a use in this beond testing out the basic idea.Thanks :)

It took me a while, but I have finally added a video. Thanks for the question, I think it makes the instructable better
