*****************************************************************************
We are redesigning a keystone arch activity that many of you are
probably familiar with. Children build a keystone arch out of five
blocks that they then can walk over. We had it made once, and the
blocks, although nice and met most of our criteria were to soft and
compress when a child of around 50 pounds sits on them. I am looking for
other materials that will be lightweight enough for small children to
handle, soft enough to not knock someone out when they sail across a
room, yet sturdy enough to work under compression. Any suggestions would
be helpful. Thanks
