What would happen if you ate one of those silica gel packets?

Well, for one thing, you'd be eating a misnomer. Silica gel isn't actually a gel, but a granular form of silicon dioxide (SiO2), a compound formed when silicon is oxidized.  Silica gel is synthetic but SiO2 is also commonly found in nature (I trust you've heard of sand and quartz.)

But before we discuss the consequences of ingestion, here's a quick history lesson. Silica gel has been around since at least the 1600s, but was a scientific curiosity until its absorbent properties were put to use during World War I in gas mask canisters. Walter Patrick, a chemistry professor at Johns Hopkins University, patented silica gel in 1919 and joined with Grace Davison, a Maryland-based chemical company, to further develop it. Davison began selling silica gel in 1923 but it didn't take off until World War II.

Silica gel can absorb a lot of water—about a third of its weight—without undergoing a chemical reaction or changing shape. Even when they're saturated, the granules stay dry to the touch and can be reused after heating at 250 °F for two hours. These properties make silica gel extremely useful for controlling moisture and humidity, and during the war it was used to keep medicine, military equipment and supplies dry.

Today it's packaged with leather products, pepperoni, electronics and vitamin pills and used in museums and libraries to guard against rust, corrosion, tarnishing, mildew, mold and spoilage.

Risk Assessment

So what happens if you decide to defy the warning on the packet, defy the social norms of polite society and munch on a few granules? I hate to be anti-climactic, but most likely, the answer is "¦nothing! (Of course, there are some caveats, which we'll get to in a minute.)

If you think about it, silica gel is basically man-made sand. It's non-toxic and chemically non-reactive. People who have eaten anywhere from a few beads to a whole packet have reported no ill effects. If you're curious, it's reportedly almost tasteless, like licking a postage stamp.

Why the Skull & Crossbones?

Why the warnings, then? Well, silica gel isn't completely dangerous, but it isn't completely safe. Here are a few reasons the packets come with stern warnings:

Dehydration "“ Silica gel's job is to absorb moisture, and it's going to keep doing that as you digest it. You'd have to eat an awful lot of it to dehydrate yourself, but if you did, it would dry you out in no time.

Silicosis "“ This lung disease, also called Grinder's disease and Potter's rot, is caused by inhaling silica dust and causes symptoms like scarring and nodular lesions in the upper lobes of the lungs, shortness of breath, fever, and cyanosis (blue tinted skin).

Foreign vapors and toxic additives "“ You don't know what the silica gel was exposed to between Point A and Point B. Eating a packet that came in a box of cockroach traps is definitely not recommended, but the gel could have absorbed other nasty stuff during manufacture or shipping and absorbed it. Sometimes, these things are added intentionally and packaged silica gel might have a bit of fungicide or pesticide added to it.

Another additive to watch out for is cobalt(II) chloride, which is toxic. This is added to the gel when a visible indication of absorption is needed. The cobalt(II) chloride makes the granules blue when they're dry and turn pink when they're saturated.

And the biggest reason? Lawsuits! "“ Even if the contents of a packet are plain old silica gel with no cobalt(II) chloride, and there's no silica dust present and there aren't enough granules to cause dehydration, companies have been sued over far stupider things. They're just covering their butts.

The First-Ever Troop of Homeless Girl Scouts Just Crushed Their Cookie Sales Goal

Selling 32,500 boxes of cookies in a single week would be noteworthy for any team of Girl Scouts, but it's an especially sweet achievement for Troop 6000: The New York City-based chapter is the first-ever Girl Scout troop composed entirely of children living in homeless shelters.

According to NBC News, this season marked the first time the troop took part in the organization's annual cookie sale tradition. In early April, they received exclusive permission to set up shop inside the Kellogg's Café in Union Square. They kicked off their inaugural stand sale aiming to sell at least 6000 boxes of cookies: At the end of six days, they had sold more than 32,500.

Some customers waited in line an hour to purchase boxes from the history-making young women. Others gave their money directly to the troop, collectively donating over $15,000 to fund trips and activities. After purchasing their cookies, customers could also buy special Girl Scout cookie-inspired menu items from the Kellogg's store, with all proceeds going to Troop 6000.

The troop formed in 2016 as a collaboration between the Girl Scouts of Greater New York, Mayor de Blasio, and the city Department of Homeless Services. Meetings are held in shelters across the city, and many of the troop leaders, often mothers of the scouts, are homeless women themselves. About 40 percent of New York's homeless population are children, and Troop 6000 had to expand last summer to accommodate a flood of new recruits. Today, there are about 300 girls enrolled in the program.
