That said, their 13-foot-tall robot is far from harmless with its twin Gatling gun that shoots 6,000 ball bearings per minute and can be triggered using facial expressions. An instructional video gives the saccharine yet terrifying warning, “Be careful to not cause a shooting spree by smiling too much!”

At the paper mill, an electric heat gun fell into and ignited a bucket of flammable resin during a scheduled maintenance operation. The heat gun was not permitted in the work area, but workers were using it to speed up their cleanup and maintenance operation. Such hot work was not allowed in the confined space, and the workers lacked a fire extinguisher.

Digital-era chemists may not be familiar with another wonderful piece of technology from the vinyl age: the Zerostat antistatic “gun.” These piezoelectric devices fire ions out of a metal point, neutralizing static charges. They are usually used to remove dust from LPs. However, I keep one next to the microbalance in my lab.

—Smoking Fingerprint “2,5-Dimethylfuran is identified as an ideal marker for detecting cigarette smoke” Of the thousands of molecules released when someone lights up a cigarette, 2,5-dimethylfuran has been deemed the best “smoking gun.” This marker molecule could be used to evaluate workplace safety and quantify cancer risks.

For example, Gore goes on at some length in chapter one about the potential of three-dimensional printing and concludes with the factoid, “Some advocates of more widespread gun ownership are promoting the 3D printing of guns as a way to circumvent regulations on gun sales.” Really? I thought to myself. On the front page of the next day’s Washington Post was an article entitled “Parts made by 3D printers may stymie gun-control efforts.” Gore is very much on top of technology trends. Gore ranges widely in “The Future,” delving into history, economics, sociology, and broad swaths of science and technology to advance his argument that “there is no prior period of change that remotely resembles what humanity is about to experience. … Nor have we ever experienced so many revolutionary changes unfolding simultaneously and converging with one another.”

These nitrogen-rich molecules are considered "greener" than traditional explosives because they generate fewer carbon-based by-products that can damage artillery gun barrels and the environment. The researchers' calculations indicate that N2H5CN7 has the highest detonation pressure and velocity of the new compounds—values that exceed those of the powerful explosive RDX.

Contrast this with the situation of another group of hobbyists, gun enthusiasts. The equipment they need for their hobby is far more dangerous if misused and is readily available, yet they continually complain they are an oppressed minority because there is a limit to the number of guns they can buy per week and they have to wait a few days to get them.

And the change likely will spur a discussion, much like in 2016, when Apple changed its pistol emoji to a water gun. Broni says the move was likely political. The gun emoji change was controversial, but other companies that use emoji soon followed. He expects that the same will happen with the syringe.

In this technique, the metallic components are codeposited from three sputter guns arranged at a 90 or 180 angle from each other around a rectangular substrate. The amount of metal deposited from each gun varies with the distance from the gun. Thus, smoothly varying composition gradients of three metals are produced on the substrate in the presence of oxygen.

Particulate or nanofiber powders are applied to the sheet via liquid-based methods, sputtering, or with an electrostatic powder-coating gun. Then stacks of the coated sheets are twisted into scrolls of yarn, with the particulate matter filling the scroll “galleries,” or spaces between the support material.
