It's been 5 weeks since my last photo challenge post. The main reason the challenge was on hiatus was Grad Girl's big exam that required a lot of effort to get ready for. Now That she's past that and a lot of our travel is done for a bit, we were all ready to get back to getting photos for the last challenge.
This one was harder than we expected. To be honest, I struggled the most. I didn't get my photos till last night and it took some set up and patience.

| Kate: Just Smoke |
It took me several attempts at generating smoke before I found one that worked. But all the effort paid off, I ended up with several shots that were interesting. This one was my favorite.
My Guy captured this shot on his way out of town to photograph the comet.

| My Guy: Distant Fires |
It's been incredibly dry here. We'd not had any rain for two to three months. We did finally get some rain on Wednesday and the forecast is for a rainy weekend. It's definitely needed. There were grass fires one county over from us that required evacuations last Tuesday. I think the firefighters were able to prevent any homes from burning, but it was definitely scary for the residents.
Grad Girl as usual found something from her experiments.

| Grad Girl: Toxic Orange Smoke |
It may be a little hard to see, but there is a definite cloud of orange smoke (technically it's a vapor) in the flask. This is red fuming nitric acid, which is very concentrated nitric acid and a very dangerous inhalation hazard. It's one the reagents Grad Girl uses in her lab work. If you were to buy a bottle of nitric acid for general lab use, the concentration of that nitric acid is about 68% (the rest is water). Red fuming nitric acid is 86% nitric acid. Definitely a liquid that has to be handled in a well functioning fume hood.
My Guy and I thought this challenge was hard. He pulled the card for this week's challenge. It's harder.
I actually have an idea. We'll have to see how that pans out. Should be another interesting week of photos.
