Dear Heloise: I remember that you had a simple PREWASH-SPRAY recipe. I can't seem to find my copy. Could you please reprint it? -- Haddie in Chicago You bet I will, and this will save you from spending money on commercial products. It is a really easy solution that you can mix up for just pennies. Mix equal parts water, household ammonia and dishwashing liquid. For example, combine 1 cup, 1 cup and 1 cup. Make sure to use dishwashing, NOT dishwasher, liquid. Mix well, and put into a clearly labeled spray bottle.

A Texas organization announced Monday that it has designed and fired a plastic gun that can be assembled using a 3D printer and publicly available blueprints. Dominic Basulto writes that the development will pose a challenge for legislators: What makes the 3D-printed gun so dangerous is that it muddies the waters of the gun control debate in a way that makes it harder for proponents of gun control and technologists to agree on exactly what they mean. We're now able to imagine, create and...

Imagine if your coat could wrap itself around you a little bit tighter when the temperature dropped. Or what if your car drove you to work instead of the other way around? Well, don't expect anything in time for the next snowstorm or morning commute. But some experts predict the technology that could lead to these capabilities is likely to start entering the marketplace within the next five to 10 years. Robots, multidimensional printers, sci-fi-style polymers and other new technologies are beginning to...

Reader: Recently my department moved to a different work space, and I've been sitting in a cubicle two feet from a large-capacity printer. Almost immediately, I noticed the constant smell of toner and chemicals, which has given me daily headaches. I have never raised a fuss about anything at work and am generally a conflict-avoidant person. But breathing in chemicals 40 hours a week is not okay with me. The easy fix would be to move me (not possible at the moment) or the printer to another location.

Twenty minutes into his State of the Union address last week, President Obama entered the realm of uber-geekery — three-dimensional printing. The magical devices capable of printing prosthetics, violins and even aircraft parts have the potential, the president said, "to revolutionize the way we make almost everything. " Forty miles away from the Capitol, in Glen Burnie, Md., Travis Lerol is proving Obama's point — with guns. In a spare bedroom, where an AR-15 rifle leans against the...

LAS VEGAS — When Ford wants to try out a new transmission part, an engineer sends a digital blueprint of the component to a computer, and what happens next once seemed like the stuff of science fiction. Inside a device about the size of a microwave oven, a plastic, three-dimensional version of the component begins to take shape before your eyes . After scanning the design blueprint, the gadget fuses together a paper-thin layer of plastic powder. It repeats, putting another layer on top,...
