Thanks for your help!!! Regarding the muffin fan.... Would a normal travel/ battery operated one work as my electrician skills are bill haha
I am also building the gas mask. I love your design, and it is very similar to the idea that I am going with. I was wondering what size globe you ended up buying? I don't want it to be huge, but I don't want to actually suffocate the actor either.
Also, to others who have built this, does the fan seem necesarry or is the bubble big enough to provide some circulation? Thanks so much!!
