Night

I have a n/c momentary button. I don't have time to buy a n/o button so I need to use a relay to make it work. My co-worker says it's possible but I'm at a lost when it comes to this. Can anybody help?

I have a fireplace with a stone back wall. I was doing renovations in the room behind it and removed a section of the wall to reveal that those stones aren't set properly and there are many holes in between them along with loose stones. I'd like to know the best way to fill those holes. My first thought was something like spray foam but I wouldn't want that near a fireplace.

Thanks.

I'm a male and have this similar wedding ring:

It's tungsten and cannot be resized. I was wondering if there's a way to add a little something to make it thicker. It's perfect when winter comes along and my hands swell due to cold weather but in summer, I can take it off by simply putting my hand down and wiggling it.

Thanks.

We bought our first home a year ago so we're still new to things we need. I noticed (after a squirrel died in the stack) that we don't have that mesh that goes at the tip of the cap to prevent these things. I was told you only need it for the summers months and take it off when you start using the wood stove. Any ideas?

Thanks

If i'm on Facebook on my iPhone, is there any possible way to know i'm on while the other person is using it on the desktop using the same account? I intend to strictly look at the messages once they've been opened already by the desktop user and not open them myself.

Thanks
