Bottlebrick Keyhole at Sayre High School: It Happened!

Zarif Robinson wingspans the progress on the keyhole garden
 built over the summer at Sayre High School, West Philly
And there it was: After two-plus years of neighborhood environistas compacting miscellaneous plastic into 20-oz. soft-drink bottles, a keyhole garden arose in the garden atrium at Sayre High School at 58th and Walnut streets. Eric Sherman, a nutrition educator for the Agatston Urban Nutrition Initiative working at Sayre, made it happen! 
Sherman had been planning the project since he agreed to take our stash of 600 bottle bricks. Over the summer, he and his college interns worked with a group of high school students on the keyhole garden, now waist-high, a U-shaped structure that will eventually be filled with all manner of ingredients to become rich soil. (When planted, a keyhole garden can be easily maintained from the “keyhole” space in the center.) 
The students described their construction experience at a celebration of summer projects connected to the University of Pennsylvania’s Netter Center for Community Partnerships. “Keyholes require a lot of cement. They save the environment. They are creative, very messy, beautifying, and decrease pollution.” Eric and his crew built with cement; the students really enjoyed learning and participating in the construction itself.
Meanwhile, at Ramah Day Camp in Elkins Park, nature educator Corri Gottesman collaborated with Wendy Smith and her family on a bottle brick garden bench. Wendy’s husband, Michael Posner, *really* likes an aloe drink that comes in square bottles. Wendy recruited other camp families to start bottle bricking for the Ramah garden, and by the start of camp they had several hundred bottle bricks at the ready. 
Gottesman elected to build with cob, a natural cementing material. Campers loved mixing mud, sand, and straw, slapping it on the bottles, and gradually building a solid bench. Construction will continue into the fall.
The Weavers Way Environment Committee has been at the bottle brick project for several years now. Here are some lessons learned:
It’s a long way from an idea to a reality. I wrote about bottle bricks and keyhole gardens in my book on effective tools for poverty alleviation. It seemed to me that bottle bricks would be great for building a keyhole garden. However, I don’t live in the developing world, so my theory would have to be proven in our community. Fortunately, the Weavers Way Environmental Committee folks could see the potential and many of them quickly adopted the personal habit of brick-making. But we needed a partner. . . . 
Matching supply and demand is hard. People were making the bricks, but it took quite some time to find a “project manager.” Logistical and labor challenges kept our first two partners from being able to follow through. We are very grateful to Eric and Corri!
People’s ideas about following instructions vary widely. Bottles bricks of all shapes and sizes started appearing, not just the 20-oz. size we had requested. Bricks need to be UNIFORM. Moving forward, we will heartily discourage weird sizes and shapes, unless someone can commit to making a lot of them. (Hello, Michael and Wendy!)
Our suggestion to other project initiators: collect the empties you want to use and distribute them, along with directions.
Keeping track of inventory is hard. We stored bricks in boxes, bins and crates at several different venues. Bad idea! It was really difficult to discern how many we had. In the future, we’ll be using a standard size box with handholds. They will be easy to stack and the brick count for each box will be the same. Sure, it’s Warehouse 101; now we’ve learned our lesson. 
People are committed – dare I say addicted?— to bottle brick making. It is a hands-on, satisfying solution to the problem of what to do with the multitude of little discards in our lives. Moving forward, we need to do more projects. Have one to pitch? We are eager to hear your idea!

Like a Hand and Glove

Well, look at that. Now we have thick, flat, hollow tiles!
One of the challenges we discovered in our prototype is that the depth of the bottle caps requires a really thick layer of Thinset. And, the thickset inside the tiles didn't dry very quickly.

As if by serendipity, we discovered that the disks from peel-cap jugs pop RIGHT INTO the solid color screw caps. As if they were desigined to do this.

So we are collecting those too. Actually, tons of people were already contributing them, but now we are actively seeking them. Their technical name is snap tops, but no one knows that.

What we now have is a thick, hollow flat back tile. We could put more material inside it. The smaller screw tops from aseptic boxes of milk and soup also seem to fit well, to fill space.

We are learning!

Bottle Cap Mosaic Collection: Amazing Colors Are Adding Up!

The bottle caps are adding up! White is the big winner.
Our goal for the mosaic mural on FoodMoxie's Keyhole Garden (built of bottle bricks) is 5000 bottle caps. I suspect we are close, but since we likely will not have a keyhole garden to adorn until late spring 2017, there is time to collect many more bottle caps than that. What is not used can be moved forward to a future project.

Sorting them by color has been the next logical step. Many of the donated caps have writing or embossing on them, so those will be donated to Gimme5.  We are accumulating lots of the desirable completely solid caps. And, we have a few donors who are saving tops from Ensure Nutrient Supplement - they have an aluminum plate on the bottle caps that is relflective and very cool.
Open bins are the most efficient way to toss bottle caps in,
by color.  The color distribution will impact Eurhi's design.

These metalic caps will add sparkle and pop
to the design. The deeper liquor bottle tops are
great, though we're not sure about how varying
depth will work out.
I have collected tubs to store the caps. The most common, after white, are dark blue, yellow and red.  We are also collecting the peel off disk style bottle caps, as backing.
























There are many shades of orange plastic caps, many from citrus drinks

There is a bin/tub at Across the Way,
Mt. Airy, for dropping off caps.
Thanks for all your contributions!

Bottle Cap Mosaic Workshop - Global Ed Forum



At the Global Ed Forum, 2016, here in Philly - my workshop participants came up with a really cool design, playing with my growing collection of bottle caps!

Building Blocks of Peace at Parkway Peace High School, Philadelphia

Peace High School Students, in East Mount Airy, cooperate on
creating bottle bricks filled with electronic waste - 2016
I was invited to present a workshop at the Parkway Northwest High School of Peace and Social Justice at their all-school event on International Peace Day, September 21st.

Remarkably, the day's theme was "Building Blocks of Peace". The school rounded up electronic fill from PAR-Recycle Works. This really makes the bricks win-win, since the electronic cords et al are weighty and not recyclable. They had even cut up all the cords for us into small pieces.

Below, one of the bottle brick fabricators performs the "stress test": can you stand on the bottle without it collapsing? He was sceptical, but the brick held!

Plastic Bottle Cap Mosaic Grouting Experiments - Eurhi Jones and Betsy Teutsch

Eurhi Jones working on grouting detail. Now we know we need smooth-top
bottle caps! The ones with designs got clogged with grout!
Today Euhri came over with grouting equipment. Our prototype had dried, and most of the bottle caps were well-attached to the thinset. A few larger ones were not and our first conclusion was: no deep big caps, even if they are visually fun.

Grouting is tricky, especially on an uneven surface like we created. So our next conclusion was that a few slightly deeper caps will add an interesting dimension, but we will try to be more uniform.

Grouting proceeded and then we hit a real challenge. We had included a bunch of bottle caps with a very cool citrus design. But the grout got stuck in all the crevises. It is much harder to clean grout of plastic caps than ceramic or glass. We will research alternatives. And possibly daub oil on the surface of the caps before grouting.
We resorted to using toothbrushes and toothpicks to clear off the
grout that stuck to the surfaces of the bottle cap tiles. Figuring
out a work-around!

The great news is that once the grouting is done, our caps look quite beautiful - my friend Mindy likened them to the sea glass that she collects. They really no longer look like plastic junk, but instead, beautiful circular tiles. See for yourself!
The left side has been grouted. See that some of the tiles are full of grout :-( and that the tiles on the left look much more mosaic/tile-y than the exposed bottle caps on the right. Success!
