Toothpaste Capsule

When travelling, I store toothpaste in a 10 gram round pill container. I bought mine from The Container Store. Depending on the thickness of the toothpaste, I find that I can get 14-20 servings out of this volume of container. I brush my teeth twice per day, so this translates to 7-10 days of travel.

These containers probably wouldn’t be leak-proof if they were used to store a liquid, but they are up to the challenge of securing a higher viscosity substance like toothpaste.

Toothpaste Capsule

After using these for a while I bought a set of 15 gram containers, thinking that this would allow me to carry a two week supply. They accomplish that, but the containers aren’t as nice. They have fewer threads, which make me think it is possible for them to pop open in my bag (though I haven’t experienced this), and their slightly greater height makes them a bit less convenient to pack. I stick with the smaller containers, which are an adequate volume for most of my travel.

I think these toothpaste capsules are superior to travel-sized toothpaste tubes. I can fill my container with whatever toothpaste I prefer, instead of being limited only to those toothpastes for which I can find the elusive travel-sized tube. When I run out, I can refill the container with whatever toothpaste is around, instead of wastefully disposing of a used tube and beginning the hunt for another travel-sized tube. The capsule is easy to fill, unlike other options for repackaging. And they don’t take the time and forethought (and low-humidity environment) that is required for Mike Clelland’s toothpaste dots.

After finding that these toothpaste capsules worked well for me, I began using an identical pill container to carry sunblock. Sunblock can be repackaged more easily than toothpaste into mini dropper bottles, but it’s impossible to clean those bottles out after use. The pill containers are simple to empty and clean, and applying sunblock from them is just as easy as it is out of a dropper or squeeze bottle. Unfortunately the toothpaste capsule and sunblock capsule look identical in my bag. So now I have the habit of sniffing my toothpaste and sunblock before I use it to make sure that I don’t brush my teeth with sunblock or rub toothpaste into my skin. I should probably label them.

Wallet Shims

I bought a SlimFold Micro Wallet last year. It does a pretty good job of holding some cash, a few cards, and otherwise staying out of the way. The inside of the cash compartment has little wings of the softshell material that create interior pockets for additional cards. The wings also provide access to the two other materials that make up the wallet: foil shields for RFID blocking, and pieces of plastic that provide structure to the wallet. Both of these materials just sit inside the pockets and are easily removed.

The two pieces of plastic are about 85mm x 73mm. At 0.25mm thick, they’re just thick enough to perform their intended purpose, but aren’t all that useful for more nefarious purposes. At the suggestion of a friend, I replaced these two pieces of plastic with shims.

I ordered a set of Super Mica Door Shims from Red Team Tools, which comes with sheets in two thicknesses: 0.35mm and 0.50mm. Using the wallet’s included plastic as a template, I cut out one piece of each thickness and inserted them into the wallet. They make the wallet a little stiffer, which I haven’t found to be either good nor bad. But more importantly, they allow me to open doors similiar to how you might use a credit card. I think it’s a great modification to the SlimFold. As previously suggested, it’s a good travel option.

Residual Oil Remover

Late last year I ran out of lens cleaner. In the past I’ve never made an informed purchase of lens cleaner, opting instead for the free bottles given out at optometry offices or whatever generic bottles were presented on the counter of the closest drug store. This time around I thought I’d look to see if there was any specific product worth purchasing. I assumed that there were probably picky photographers who had performed a survey of cleaners for their camera lenses, and that their conclusions would apply to other optical surfaces.

Surprisingly, I found only one useful review: a 2013 post on on the Digital Photography Review Forum, which outlined a testing method for cleaning solutions and concluded:

Three branded cleaners out of about a dozen, after 5 test repetitions, walked away with the honors. They are: Zeiss Lens Cleaning Solution, Nikon Lens Cleaning solution and ROR Lens Cleaning Solution. At the bottom of the list was surprisingly, Purosol, that tied with straight distilled water for having absolutely zero emulsifying properties for removing skin oil in all 5 of our test repetitions. When I spoke with the Purosol folks, and asked “How does NASA use your product and for what cleaning purposes”, I was politely told, “That information is classified, and, we unfortunately don’t know!”

Between the 3 top reviewed products, I flipped a coin and ended up purchasing ROR, or Residual Oil Remover.

ROR certainly works. I use it on my Rudy lenses, my laptop screen and external monitors, as well as the screen of my phone. But because I made the purchase after I was out of my previous cleaner, I wasn’t able to compare it to anything else for a couple months. Later on I found a partially used bottle of generic lens cleaner from my optometrist and was able to do a comparison. ROR cleans better with less rubbing.

I don’t know what the contents were of that last bottle of generic cleaner, or how it compares to the other cheap, generic cleaners that I’ve used in the past. But I am happy enough with ROR that I will continue to use and recommend it. I have three bottles stashed around my frequented areas at home and work, and appreciate its ability to keep the clarity of my optical devices at a maximum.

Houseplants probably don't improve indoor air quality.

In reponse to the oft-quoted NASA Clean Air Study, The Altantic writes:

[T]here’s nothing especially wrong with Wolverton’s 1989 study. Its results “fall right in line with other stuff that’s been measured in the literature.” But taking its results at face value significantly overstates the power of plants, he said. Wolverton measured whether houseplants could remove VOCs from an airtight laboratory environment. But a home is not a hermetic chamber. It has open windows and doors, drafts and leaks, and much more clutter.

Recently, Waring and his colleagues reanalyzed all 195 studies that have examined whether houseplants can filter the air. They found that some types of plants can remove higher amounts of VOCs than others. But once you factor in the effects of working in a large room, none of the plants are able to do much.

Waring told me to imagine a small office, 10 feet by 10 feet by eight feet. “You would have to put 1,000 plants in that office to have the same air-cleaning capacity of just changing over the air once per hour, which is the typical air-exchange rate in an office ventilation system,” he said. That’s 10 plants per square foot of floor space. Even if you chose the most effective type of VOC-filtering plant, you would still need one plant per square foot, Waring said.

The Tube Roll

I carry a spare tube underneath my saddle.

The Tube Roll: Mounted

  • The Tube Roll: Unrolled
  • The Tube Roll: Rolled

With my Schwalbe Marathon Supreme tires I rarely get flats. When I do, I usually prefer to use a patch, but sometimes you need to replace the tube. To protect the spare tube from the elements – UV rays, abrasion from dirt, etc – I wrap it like a burrito in a piece of black Tyvek. This is then stuffed underneath my Brooks B17 and secured to the rails with a 12” nylon buckle Voile Strap.

The package is easy to get to when I need it, doesn’t move until then, and isn’t very visible unless you’re looking at it. When I moved the spare tube from my pack to my bike, I wanted to avoid a noticeable bag like my Revelate Jerry Can. I’ve yet to have anyone steal this setup, but if they do, I’m only out $5 for the Voile strap, $8 for the tube, and a few pennies for the Tyvek. I can live with that.

In the case of a tire blow out, I’ve wondered if a piece of the Tyvek could be cut, folded, and used as an emergency boot like a dollar bill. I have not had the opportunity to test this, because I buy good tires that don’t blow out. The repair kit I carry in my bag also contains a couple actual reifenflicken, more so because carrying them increases the opportunities that I have to say reifenflicken than because I feel I actually need them.

While I appreciate the resurgence of personal email newsletters as an alternative to the toxic walled-gardens of Social Media™, I much prefer consuming that type of content in my feed reader.

For discussion groups, where I’m going to respond to messages and follow threads, email is great. My relationship with the newsletters I subscribe to is that of a consumer, and for that interaction I want good old HTTP and feed syndication. Kill the Newsletter is a free service that generates Atom feeds from the email sent to an address. I use it to keep newsletters in my feed reader where they belong.

The Burrito Bag

As a cyclist in San Francisco, one of the great challenges in life is how to carry all the burritos you’ll consume. The quality of a burrito as a fuel source is directly correlated to its slopiness. If placed directly into a backpack, it will inevitably leak through the imperfect foil wrapping and soil neighboring equipment.

To solve this problem I revisited my DIY Tyvek Stuff Sacks from years past and created the Burrito Bag. The burrito is placed into the Burrito Bag for transport, containing any mess, which is later easily rinsed out.

Burrito Bag

The Burrito Bag is constructed from black Tyvek I had from another project, rather than a USPS Priority Mail envelope. I cut out a piece 13” x 16”, folded it in half and used the awl from my Expedition Sewing Kit to close the bottom, side, and create a channel for a piece of Technora (because it’s cool) and cordlock to use as a cinch cord.

The Burrito Bag is strategically engineered to contain dual burritos, or a single burrito with a generous side of chips. Actually it was patterned off of one of my original Tyvek stuff sacks, which I still use to contain my Trail Designs Ti-Tri cook system. It seemed like the right size for this application.

The Burrito Bag weighs in at 8 grams (0.3 oz), and when not in use folds down to a size smaller than that of the napkin you forgot to grab on your way out of the taqueria.

The Burrito Bag is multipurpose. Despite its name, it is also capable of holding a shawarma wrap from the neighborhood Lebanese joint. I even once used it to takeaway a sushi roll.

Tightening the Bedrock Cairn

I bought a pair of Bedrock Cairn Adventure Sandals when they were released back in 2016. They are my favorite sandals. In addition to being great everyday and hiking footwear in the warmer months, the Cairns are my preferred running footwear year round.

Bedrock Cairn Running

My only complaint with the Cairns was that the adjustable strap would occasionally slip, loosening the sandal. The webbing would only slip a couple of millimeters over a handful of miles. If walking or pedaling I wouldn’t notice it, but when running this allowed just enough movement of my foot across the bed of the sandal that I would eventually develop a hot spot if I didn’t reach down to tighten the strap every 6 miles or so.

I mentioned this in one of Bedrock’s customer surveys. They reached out to me and suggested that when tightening the strap, rather than keeping the loose end of the webbing inline with the part connected to the wing, I kink the webbing slightly forward. This allows the buckle to get a bit more bite. The added friction from this adjustment has eliminated any loosening of the sandal on my runs.
