Fail On Plastic Guns
—Fail On Plastic Guns “” I wish C&EN would discuss chemistry and not push political views. The article “The Desktop Arms Plant” reports on an upcoming technology that has a lot of uses (C&EN, Sept. 30, 2013, page 11). Why not report on how it can be used to make experimental robotic parts or machine prototype parts?

Making Everything In The Desktop 3-D Workshop
Moreover, 3-D printers have already made semiautomatic weapon parts of high quality, a development that may prove more dangerous than a crude polymer gun that can fire a single round. The making of guns and gun parts has grabbed a lot of attention, but it is a small corner of the nascent 3-D-printing world.

Your ducky’s microbiome, glow-in-the-dark squirt guns
Glow guns If you are going to sacrifice your kid’s tub toy for science, maybe do it after an evening bath when you can distract him or her with a toy that actually benefits from its brush with biology. Get two or more BioToy squirt guns, and add some clean water—not from the tub—and a set of special tablets.

Judge blocks 3-D printed gun files from going online
—Judge blocks 3-D printed gun files from going online “States sued over fears of untraceable plastic guns” A federal judge in Washington state has issued a restraining order that will prevent Defense Distributed from sharing design files for firearms online. The second amendment advocacy organization had planned to make the blueprints, which instruct three-dimensional printers to make firearm parts out of polymers, available today. 3-D printed firearms are the subject of much dispute over their legality, public impact, and technical feasibility.

Troubled Aftermath Of An Explosion At Sea
These investigators found that the most likely cause of the explosion was frictional ignition of the propellant used in the gun, due to improper ramming. The Navy has since retracted its original conclusion. Thompson gives the background of recommissioning mothballed battleships in the 1980s and the feel of the people and conditions aboard Iowa, especially within her gun turrets and supporting magazines. The book's schematic illustrations of a 68-foot-long gun and its gun turret are an excellent aid to understanding what happened as the propellant ignited in the gun barrel and produced a fireball that led to further explosions of propellant stored in the gun turret. Photographs not authorized by the Navy of the damage the explosion caused within the turret are also revealing.

Plasma gun sprays out high-quality graphene
—Plasma gun sprays out high-quality graphene “The fast, low-cost method splits graphite particles into graphene flakes, showing promise for mass production” Graphene has slowly made its way into sports gear, anticorrosion coatings, and even fabric face masks. But widespread use of the strong, conductive material hinges on making high-quality graphene affordably and at large scale.

What’s artificial snow, and how is it made?
Ski resorts, hoping to extend the season or simply enhance existing natural snow, pump water and pressurized air uphill to “snow guns” stationed along the slopes. The snow guns atomize the water and spray out a long plume of fine droplets, which hopefully freeze before hitting the ground. In 1980, the Olympics held in Lake Placid, N.Y., became the first Winter Games to use machine-made snow, but they weren’t the last.
