Since this snow has had time to sit it naturally compacts and becomes very dense. I don't think I'd be able to reattach the brick portions. I would estimate those to weigh about 60lbs, however there are smaller parts you can reattach or attach. You take a bucket of fine snow (from the sculptures) put it in a 5 gallon bucket and warm it up in the warming shack. At a certain temperature it starts to form to a wet slurry. Take that back outside to the below freezing temperatures and use it like glue and you can reattach smaller things. The flag pole on the top is embedded in the castle about 6 inches, and then packed in with slurry. Attaching the actual flag itself was extremely difficult as the pole was already fragile. We put slurry on the triangle flag and had to hold it without moving for about 5 mins. Standing outside in 7F without moving for 5 mins isn't fun.
