Chris, I'll tell you about the lion my students and I built at the request of the local Lions Club some years ago. Cardboard boxes, chicken wire and masking tape were the base, papier mache was the surface body. It was a wonderful lion, huge, about 8 feet tall and maybe 4+ or more feet wide.
We made it in the classroom, took weeks to build and perfect. It was beautiful and jawdropping amazing.
I am a very good art teacher, but one who has no common sense or practical application or something.
When the Lions Club men came to pick it up, it was too big to go through the classroom door.
We had to saw his legs and haunches off, carry the parts out, and then add all the parts and pieces back on.
Duh.
With this bowling ball project, I need all the help I can get.
See?? That's why I'm here.
