Next today, gas prices, they are free falling, and it looks like they are only going to get lower.The U.S. national average for a gallon of gas was 3.26 one year ago. It's about 2.67 now. By next spring, analysts predict it will be below two bucks a gallon. Why?U.S. oil production, for one thing, it's booming. Even though a method called hydraulic fracturing or fracking is controversial, it's yielding a lot of oil.Also, the price of crude oil, the biggest factor in the price of gas, it's dropping.There's less demand for crude in Asia and Europe where economies have slowed down.All this is good for us, drivers, it's not for countries whose economies depend largely on crude oil sales.The Smithsonian Institution, the largest museum complex in the world, has a new way for you to wrap your mind and your hands around history.It's using three-dimensional imaging to scan everything from Abraham Lincoln's facial structure to a T-Rex toe.And if you have access to a 3-D printer, you can use it to create replicas of priceless and matchless museum artifacts.It's a-look at the crass commercialization part of this, but we are a few years away from like really, really good Halloween costumes.It's up and coming. Yeah.How long does the president have to sit for this?It took from the minute he walked into the room until we were done with the process seven minutes.
