"all i know is if there is one installed in every bedroom there is a better chance to get out." My concern is they create a false sense of security. I just don't see a kid or an older person getting down one of those. My niece is a very adventurous 9 year old and I don't see her stepping out a window in the dark and going down a ladder that isn't rigid. I would be terrified to do it but could. Most people are nervous on an 8' step ladder. Being diligent about maintaining your smoke alarms will do a lot more to get you out in time. Smoke alarms are triggered pretty easily, in my experience. Make sure you have them not just where code requires but where it makes sense. Our house more than required by code. For example, we have one in the laundry room. Many fires start there and could smolder for quite awhile before the smoke reaches the detector in the kitchen 20+ feet (and through a closed door) away. You should have heat and/or smoke detectors in the basement, attic, garage, laundry room, kitchen, each floor, every bedroom and outside every bedroom in the hallway. Don't allow smoking in your house. Don't allow guests or children to have candles in their bedrooms. Make sure all candles used (in kitchen, dining room, etc.) are extinguished before you go to bed, before you leave the house or before you take a nap. Maintain your chimney flues. If you have the ladders what will the children be taught? If the smoke alarm goes off open the window, drop the ladder and go out? Without knowing if there is a fire or any danger? Without knowing if the parent will just walk down the hall and help them? In the middle of winter? Can the child even reach the window lock and remove the screen? I think it makes more sense to teach them to close their bedroom door (but not lock it) and then open the window and wait at the window. If you live in a place where the fire department is very slow, keep a ladder somewhere on your property and climb the ladder yourself and bring them down if you can't get to them from inside the house. Stash an ax somewhere as well in case they don't open the window. This is one reason I don't like houses with first floor masters. Our bedrooms are all on the second level, there is little chance a fire would be between us and anyone in the other bedrooms. If necessary we can go to a bedroom with the porch below. DH can drop down and then help anyone else. I might break an ankle, but I could drop down as well if necessary.

Have no experience.

If contemporary is your style, then, yes, go for it. Although I don't have a contemporary home, and my dining room light is not at varying heights, it did make me think of this light. Here is a link that might be useful:

My DD and I have painted the inside of glass ornaments as gifts. It is super easy, however I would be wary of using this method on a nice glass vase without a trial first. I can't recall where I found directions, but the steps were basic. We poured a small amount of 2-3 colors in alternating "stripes" into the ornaments, swirled around slowly for complete coverage, and then placed in a secure area (we used the ornament box) for 3 days. Each day we had to turn the ornament a 1/4 turn. It did take several days for the paint to dry completely so it would pool on the bottom, and that's why you do the daily 1/4 turn. We used regular acrylic craft paint that you can get in the little bottles at the craft store. The best ornaments - and they were stunning! - were those where we used closely related colors in a pearl finish, i.e. lavender, purple, and silver.
