I came into Confederation Park, where a videographer was set up beside the ice sculpture marking the centennial of the National Research Council. A man was setting up behind one of the two side sculptures with the dates. He lit up what looked rather like a welding torch, which was linked to the device you can see in his hands here. He directed the fire at the back of the sculpture, carefully applying the flame to the surface while the videographer filmed the process. I took several shots. The sculpture was none the worse for wear.
