It's snowing in our Dome

OK, it's not actually snow, but the blowing of the polyurethane foam sort of looks like snow. The entire floor is covered in this blowing white stuff. Yesterday they managed to get about half of the required 3" sprayed on the inside of the dome. Today they will be spraying another half inch, then placing the hangers to tie the rebar on. Once all these are set, they will be adding another inch of foam. The plan is for this to all be done today. Then Tuesday (Monday is a holiday) they will come back and spray an inch or so of concrete on the inside and then, once it hardens, start putting the rebar around that to reinforce the whole dome. So, hopefully by the end of next week we will have the entire 8" of concrete, with all plumbing and electrical, inside our dome and that phase will be done.
