If you like dogs more that you like parades, here are just the dogs from Sunday's Easter Parade.  Woof!

Well, here it is, finished!  My week of experiments extruding ice through holes in a pipe, from the pressure of the water expanding.  If you want to know HOW I did it, read below.  Otherwise, just enjoy how fascinating water can be!

https://youtu.be/nbiEfr5FxEA

Water, expanding as it freezes, squeezes pre-existing ice out of holes.  After reading the invaluable blog linked below, I wanted to try this myself, but to film it happening as a time-lapse.  I modified the method in the blog slightly, for convenience.  I used 1/2-inch galvanized steel or black steel pipe, based on price and availability.  I bought a 5-inch piece and a 4-foot piece, a connector, and two end caps.  I cut a slot in one cap with a wide blade, and later added a small home.  I screwed this onto the short pipe, sealed the holes with plastic wrap and rubber band, filled it with water, and froze it in my freezer.  I then chilled a container of water outdoors until it had ice on top.  At night, once the outdoor temperature was below -4C, I removed the plastic from the small pipe, screwed it to the large pipe (using masking tape to seal the threads), filled the large pipe with the cold water, and screwed on the cap.  I laid the pipe almost horizontal, with the ice end lower.  As the water froze, it expanded.  With nowhere else to go, it squeezed the ice through the holes, making the patterns seen here.  A couple times I divided the slot in two with a nail.  I also tried horizontal and vertical layers of coloured water.  I was going to go back and get more caps and try different holes, and try flattening the pipe instead of using a cap, but didn't get back to Home Depot.  It was March when I started, and there weren't that many cold nights.  The nights were also getting shorter, so that sunrise happened before the experiments were over, messing up my lighting.  Temperatures of -7 or so worked best.  -12 seemed to make the ice more brittle, and it broke off as it extruded.  At -4 it didn't freeze at all before morning.  Perhaps the pressure lowered the freezing point.  I don't know why some extrusions were smooth and clear, and others were jagged and white.  

I gratefully acknowledge Dr. James R. Carter's blog at http://my.ilstu.edu/~jrcarter/ice/extrude78/ for inspiring me to try this, and giving me the info. on what pipe to use.

Liberal leader Justin Trudeau got into the swing of things at Pacific Mall Thursday, trying out Lion Dancing!  (I wonder if any cameras were rolling when he leaped over the railings off the small catwalk at the back of the stage!)

Some more Dave-foolery, this time water freezing in jars finally blowing the lids off!

My day at Sunday's Easter Parade, followed by a visit to the beach.  Lots of dogs in their Easter finery!  A few Star Wars characters too...

A short set of clips from the St. Patrick Parade.  County Antrim, where my cousin's grandparents are from.  Plus Dogs, Dogs, Dogs!  A human/DeLorean Transformer.  And County Cork's "proposed" subway, a definite improvement on Toronto's!

Working my way backwards, here's some highlights of the Feb 22 Chinese New Year cultural show at Scarborough Civic Center, performed by the children and adults of the Chinese Collective Arts Association.  Sorry the audio is bad in places; my video camera can 'freak out' when there's a lot of bass!

Don't hire me as an editor if you want very short highlights! This first came in at 15 minutes; I pared it down to 11 minutes, but just couldn't make it any shorter than that, it was too good! The show itself, with singing, speeches and contests, was 2h30m.

Wanting to make the most of the unwelcome cold weather, I did a series of experiments freezing plain and coloured water while filming them.  Here is a compilation of water forming icicles and oozing out of the top of straws.  
I first used a horizontal bottle with multiple holes, letting the expansion of the water force its way out, but it only came out of the hole of least resistance.  I then used an upside-down soda bottle with a drip hole in the bottom and air hole in the top.  The air hole was a pin hole; the drip hole was barely a pin point.  If I stored leftover coloured water, I had to use a freshly-rinsed container and immediately cover it.  Otherwise a speck of dust would land in it and later plug the drip hole; that's how tiny the hole was!  I also filled drinking straws with water to see how the expanding water would push out of the top.  (The second straws, I let the top freeze first by submerging the bottom 4/5th in water.  I expected when it later froze it would force the ice out the top of the oiled straws.  Only one did so.)  All ice other than the straws is back-lit, as that makes ice glow much better than front-lighting.  (Which is why flash photos of ice won't look good.)

My wintry visit to High Park Wednesday.  The scenery was quite beautiful, in a stark way.  It was nice walking with the snow falling.  (Water may roll off a duck's back, but snow just sits there!)  Some 60 photos in this set.

Lots of snow scenes, lots of ducks, in High Park on Feb. 11 2015.

I filmed a small container of water freezing overnight.  It was snowing, but I had it sheltered.  It seems like a few snowflakes blew in and sank, except I didn't know snow can sink!  The freezing seems to start from those paths, then moves forward and reverse until it freezes solid and cracks.
