Passenger Boarding Passes with SSSS Require Additional Security Screening
By Chad Upton | Editor
For a while, I travelled every single week of the year (except for Christmas). Of all the new airports, airplanes, taxis, rental cars, hotels, motels, customs, passports, visas, bad restaurants and other necessities, airport security was the most stressful.
I have nothing to fear. I’m not on any watchlists, I don’t have a redress number, I literally don’t even take the free airline snacks with me (you have to declare them at all of the international border crossings I usually encounter). (more…)
ID is Not Required to Buy Cooking Wine
By Chad Upton
The laws and store policies around the products that require ID and the ones that don’t, are sometimes confusing.
I was in Target a while back and bought a can of compressed air to clean my dusty laptop. I was surprised when they asked for ID at the checkout.
Apparently some people like to get high from the propellant in canned air. It’s unfortunate, these are not recreational drugs, these are asphyxiates that displace the oxygen in the air, reducing the oxygen that reaches your brain and eventually causes death. The solution is to require ID for purchase, although even a 42 year old man died from “huffing” canned air.
Even when you’re using these products as intended, you should avoid inhaling the fumes and ensure adequate ventilation.
I was at Target a few weeks later, looking for ramekins to make Crème brûlée. I also needed a butane blowtorch to caramelize the top of the custard. It turns out that you can buy butane torches and fuel without ID. Thinking back to my teenage years, a blowtorch would have been much more fun than a can of air.
But, cooking wine has the most interesting story.
It ranges from 10%-13% alcohol and anybody can buy cooking wine at the grocery store. They even sell it in grocery stores in “dry” areas, where no alcoholic drinks are sold. In fact, Safeway requires ID to buy cough syrup, but not for cooking wine. Some cough syrup, such as NyQuil, contains alcohol. Other cough and cold medications contain a drug known as Dextromethorphan, which is a dissociative psychedelic drug.
My friend Molly told me about this cooking wine loophole and gave me a sample of the product. If you’ve ever tasted cooking wine on it’s own, you’ll understand why anyone is allowed to buy it. Nobody would ever consume it on its own, it’s simply awful.
Wine that is sold as “cooking wine” is usually grape or rice wine. It is then adulterated with salt, which makes it less suitable for cooking and even more undrinkable. If you’re making a recipe that calls for wine, use wine that you’d actually drink and use a wine that pairs well with the food you’re cooking.
Cooking wine has a lot of salt for coloring and as a preservative. Because cooking wine is consumed very slowly, the salt prevents acedic acid from forming and turning it into wine vinegar.
Oh, and if you’re going to make Crème brûlée, my friend Mike showed me that you should skip the butane and go with propane — it has a wider flame that heats more evenly, which gives much better results and in less time.

The Three Plants That Will Improve Your Home Air
Spring is here and the garden centers are open. It’s time to get some plants, especially for inside your home.
Indoor plants are really important. There are chemicals in and on almost everything you buy. If your air is not replenished with fresh air, it can be mildly toxic. But, with the right mix of plants, your air can be cleaned and oxygenated around the clock.
With as little as these three plants, you can have this perfect mix:
- Areca palm – (Chrysalidocarpus lutescens)
- Snake plant or mother-in-law’s tongue – (Sansevieria trifasciata ‘Laurentii’)
- Golden pothos or Devil’s ivy – (Scindapsus aures or Epipremnum aureum)
The “Areca Palm” removes CO2 and converts it into oxygen during the day. The “Snake Plant” converts CO2 into oxygen at night. The “Golden pothos” removes formaldehyde and other chemicals from your air.
Using these plants has shown significant oxygen level improvements in real world situations. Having these plants in your home can increase blood oxygen levels by 1% in 10 hours. They can reduce headaches, eye irritation, asthma and other respiratory problems.
These three plants are just a few of the many plants that are considered Air Filtering Plants. NASA has identified a number of similar plants in it’s Clean Air Study — an attempt to understand natural ways to purify air in closed spaces, on earth and beyond.

Exhaust Fans Help Cool Your Home During Summer
The upper floor of your home is likely the warmest place in your home. It’s not usually a big deal in the winter, but it can be very uncomfortable in the summer. It happens because hot air rises.
The ceiling of your upper floor also has the most insulation of any place in your home. It’s there because hot air rises — in the winter, you don’t want to lose that heat. It’s the same reason you put a hat on your head in the winter.
In the summer, that thick insulation in your attic is doing the same thing it does in the winter, trapping that heat on your upper floor. If you have a central heating/cooling system, it should suck hot air from the upper floor and mix it with cooler air. But, it’s not always running and it can’t always keep up with the hot air that is produced inside your home, from people, electronics and appliances.
A good solution is to run the ceiling exhaust fan in a central bathroom on the upper floor during the hottest hours of the day. To help, you can get an automatic timer control light switch; these can be used to run the fan and have it automatically shutoff after a certain amount of time — this might also be useful after somebody uses the toilet.
In some regions, it is even part of the building code that an on/off switch for the upper floor hallway bathroom fan is placed next to the thermostat on the main floor. It’s there so you can turn on the exhaust fan when you turn on the air conditioner (there is also a switch in the bathroom to control it from there). This is not a widespread building code, but it’s worth having a look beside your thermostat. If you’ve got a light switch there that doesn’t do anything, try it again and listen for the hallway fan.

Airplanes Refresh Cabin Air 20 Times an Hour
I was on an airplane a couple days ago and the person in front of me was coughing a lot, they sounded really sick.
I was just starting my vacation and the last thing I wanted was to get sick. So, I couldn’t help thinking about being trapped on the plane for the next four hours, breathing the same air as them.
I started to think about the air quality in general. I mean, people always talk about how bad jetliner air quality is, but I really didn’t know much about it.
I did some research and the air quality on planes, at least newer ones, seems pretty good.
Firstly, the air is not circulated from front to back, it is circulated side to side. That means you’re mostly sharing the air with the people in your immediate area, not the entire plane, which reduces the spread of germs. (more…)
Why Airplanes Don’t Always Fly in Straight Lines to Their Destination
If you’ve ever been on a flight equipped with a screen that shows the flight path, you might notice some zigs and zags that make your direct flight look like a scenic air tour. There are a number of reasons for this, but most of the time it comes down to Air Traffic Control (ATC).
Some people think that air traffic controllers are the guys that stand on the ground, waving lighted wands to guide the plane up to the gate. Those guys are actually part of the ground crew and they only have control over your flight for the last couple hundred feet before you reach the gate. The rest of the flight is controlled by someone else and it’s not the pilot.
The pilot flies the plane, but his course is being set by somebody on the ground. Those people are known as Air Traffic Controllers.
This system is a lot more complicated than it seems.
At the airport, the air traffic controllers sit up in the control tower. Those guys decide who gets to take off and land, which runways they use and when. They also direct planes that are moving around on the ground between gates and runways on the apron and taxiways. This aims to provide an organized flow of ground traffic and a safe flow of air traffic.
Once your plane has left the immediate area of the airport, the pilot must then communicate with a regional controller at an Area Control Center (ACC). If you’re on a long flight, you may get passed from one ACC to the next multiple times as you fly across the country.
Why? (more…)
