Retroreflective Manicure

2 09 2012

You  know those moments when you think of something so awesome but also so obvious and wonder “how did I not think of this before?” I had one of those last week – retroreflective nail polish!

Retroreflective means that a material reflects light directly back at its source. For night time cyclists, this means that the light from a car’s headlights is reflected back at the driver, making you look far brighter and more visible from a longer distance. Retroreflective materials are used in things like street signs and markings, high visibility safety wear, and to improve visibility of trailers & train cars.

Last year, I procured some traffic grade retroreflective glass spheres (spheres so small they’re almost a powder). I used them to turn bracelets and silk flowers high-vis in Retroreflective Goodness and to make the magnets in Bike Art Galore. The technique is easy: pour the glass powder over wet paint, let it dry & shake off the excess so there’s a single layer of glass spheres on the surface.

To apply to nails, simply embed the spheres in the final coat of wet nail polish! I did a blue stripe over a purple base coat and then just gently laid my nail down in the powder.

I only did the pinky and ring finger with the retroreflective material because this is still an experiment. The camera flash replicates the effect of headlights.

Hand signals just got way more awesome! Like with paint, the lighter the colour, the brighter it will be, and metallic colours look amazing.

So far, the retroreflective nails have worn better than just the regular polish, leaving me with another problem: how to remove it. I usually rub polish off with an acetone soaked rag but I don’t dare rub the retroreflective glass. Remember the Mohs hardness scale – glass scratches fingernail. I figure I’m going to have to invest in the type of nail polish remover where you dip the whole finger in if I’m going to have any chance of getting it off without damaging my nails. Another issue I’m having is keeping it clean. If I do up my whole left hand I’ll have to start wearing a glove (which I’m not a fan of) while I’m wrenching to prevent any bike grease from taking up permanent residence. At least one thing that I was worried about, the glass spheres detaching and getting into everything, hasn’t happened though.

Retroreflective Goodness

15 02 2011

Cyclists constantly hear complaints from drivers about how difficult we are to see (or more accurately, how easy it is not to see us). In response, some cyclists will feed an endless supply of batteries to a Xmas tree’s worth of blinkies while others repurpose dayglo highway worker vests into everyday riding garb. And that’s fine, it’s just not the way I roll.

Geneva put a little bird on her hoodie.

The retroreflective silver returns the flash right back to the camera.

When I ride, I hope to encourage other folks to ride, too, and I think that presenting bicycle commuting as something you need an ugly uniform to do safely is contrary to that goal. “Cycling clothes” need not be discernible from street clothes, they’re just street clothes that happen to be suitable for cycling (which includes  everything but the trench coat).

Haydn put some subtle stripes on his parka.

Under headlights, though, not so subtle.

Still, some of the technology being developed for safety and athletic applications, such as retroreflective treatments are pretty cool, and I am very interested in applying it to apparel without it reading as safety wear.

As well as a pennyfarthing motif on his sleeve...

... Ian also created a turn signal effect on his gloves.

Perhaps I should begin with what retroreflective is, besides a cumbersome word that spell check won’t recognize. A retroreflective surface reflects light back to the source, no matter what angle the light hits the material. This is important for cyclists because at night it reflects the light from car headlights back to the driver, often allowing them to see a cyclist earlier than without a retroreflective sumtin sumtin. It’s no substitute for a good set of lights, but every little bit can help. In the photos throughout this post, the camera flash simulates the effect of headlights.

Orange is good color for daytime visibility.

With the addition of some retroreflective motifs, it's a good choice for night riding, too.

Over the last year or two, I’ve facilitated several workshops for folks to add retroreflective accents to their own clothes. The material we use is scrap from industrial production, the process is pretty simple, and the imagination is the only limit. All the pictures you see in this blog post taken in the red room (the upstairs lounge at EBC) are of folks who spent an evening with me brightening their wardrobes with this silver film.

Brendan's strategy for choosing his motif was one of my favorite.

"Eyes" like a moth to activate the "flight" response in the most primitive parts of the human brain.

This week I’m holding another workshop (Thursday, 7pm at EBC – register by emailing courses (at) edmontonbikes (dot) ca ) for anyone who’d like to increase their visibility without increasing their geekiness (unless you want to up the geek factor, and I’d be glad to help you if that’s your steez).

As well as using the retroreflective silver film for clothing, this workshop will have another exciting aspect (hey, I get excited by stuff like this). Inspired by a really cool tutorial on Giver’s Log, I’ve got my paws on some raw, traffic grade, tiny retroreflective glass spheres – think of it as high visibility glitter.

The retroreflective glass beads I added to this orchid for my bike look like a layer of sugar.

Outside, in the dark, this lovely orchid sends more light back to its source than the red rear reflector.

Having access to the raw material means we can now retroreflectivize a greater variety of stuff (specifically, anything that can be painted with acrylic craft paint) in almost any color.

These bracelets don't look like safety wear.

But in headlights no one will miss a turn signal when you're wearing safety bling.

I’ve barely begun exploring the possibilities of this stuff, and I’m really looking forward to seeing what the workshop participants will create on Thursday. If you’re in E-town this week, come check it out! The workshop will be fun, it’s cheap and there’s still space left for last minute registrants.





24 Hours in the Slow Lane

21 08 2010

It was one of those restless summer weeknights where adventure and responsibility fight for the attention of the insomniac mind, when I decided I needed to ride. I often feel that I have to go farther away to find fresh scenery, and to push myself to go harder and longer, but this night I felt bored with that prospect, and instead opted take Poplar (my 1950’s loop frame bike) for a tootle.

The University of Alberta campus is close to home, packed full of all sorts of interesting stuff, and is delightfully abandoned and quiet after midnight, making it the perfect place for a slow late night ride (so long as campus 5-0 didn’t bust me for riding without lights or a bell).

View from a parkade top. Also, check out the reflective design on my hoodie!

I wanted to top a parkade on Poplar mostly because I wanted to feel what it’s like to do it on a single speed with a coaster brake. Turns out it was no problem at all, and I therefore have no reason to feel bad about any time in the past where I may have “encouraged” anyone else on such a bike to do it. 😛

I wonder if, in the 70's it was some art or design student's project to paint large circles at the top of a parkade...

Coasting down the ramps of the empty parkade, ducking my head because the ceiling seemed too close, I inadvertently rode into a photo shoot for a shiny black SUV. What an ad that would’ve made – sleek new car in huge empty space-age garage, and suddenly appears yours truly, smiling and rattling and rolling on a rusty 60 year old cycle. That image kept me giggling as I rolled down to street level and set off to explore more of campus.

Sculpture garden in the FAB courtyard, where steel goes to rust.

With the huge amount of construction on campus, routes are constantly changing, getting blocked off and detoured. The amount of change certainly keeps things interesting, and the temporary walkways can be a blast.

So, you're not supposed to ride through here, but when it's the middle of the night...

Not long after, with a big yawn I returned home for a second chance at sleep.

The next morning, the city was blanketed with smoke from forest fires 1000km away. Remember a couple of weeks ago when I was complaining abut the haze? Well here’s how bad it has to be for an air quality warning:

High Level Bridge disappearing into the smoke.

Everybody’s eyes and throats were burning, and everything smelt like campfire. Worse yet though, is the thought of the destruction in BC causing all this. The pressing question for me was whether or not I should bicycle commute. Sitting across from me in the living room, the answer was obvious, “Poplar, you’re going to work!” (Doesn’t everybody keep their vintage bikes in their living rooms?). There is no way I could ride that bike faster than 15km/h, therefore I wouldn’t be tempted to over-exert myself in the nasty air. I gathered some tools in case the bike acted its age and set off on my longest (non snow storm) commute.

I noticed more people taking it easy on slow bikes than ususal, and so many more people smiled and waved, more cars stopped for me – I’m not sure if was the haze or the bike. Not long after I left home, I realized I had brought neither a water bottle nor a lock, and started worrying I couldn’t safely leave my bike while I picked up something en route to soothe my burning throat. My remedy awaited in Churchill Square in the form of people giving out free mini cans of Sprite. Cold, fizzy, sweet, free liquid? Yes please! I was very happy that my coaster brakes allowed me to drink and cycle safely at the same time. Slow riding was looking better with every revolution of the wheels.

After work, where better to go for eerie, smokey pictures than a cemetery?

Baby graveyard, for extra creepiness.

I like riding in cemeteries. They’re quiet, green, with empty meandering paved roads, plus I find old gravestones fascinating.

Looking for the sun. Looking at the sun.

Next stop, a slow ride to 118th Ave for a gallery opening and some farmer’s market goodness. The guy at the fruit stand really liked my bike. I appreciate that the 118 market is chill enough that I could keep my bike with me, and that the Nina Haggerty allowed me to leave my bike inside.

Loaded up with fresh fruits & veggies and my pink tool bag, riding into the haze again.

After more errands, and some unexpected run-ins with friends, I headed back towards the bridge and the south side.

The sun was just a cold orange disc. I wonder if this it what sunshine on Mars would feel like.

The view of the river valley in the strange orange light was spectacular.

Or maybe this is just a prelude to some sort of post apocalyptic Earth.

Over 48 hours, I rode about 50 slow kilometers on Poplar, and maybe I’m just projecting, but I think she enjoyed it as much as I did. My 10km commute, not including the extra stops, was only 10 minutes longer than usual, and was far more enjoyable than I expected. I may have to take the slow bike to work again…

Smoke on the water, and fire in the sky...
