A couple Sweet Gum trees in my yard shed spiky balls from time to time. Until now, all they've done for me is to make barefoot walking uncomfortable. But I discovered they're convenient for supporting something to be coated on opposing surfaces. Three of them make a tidy tripod, with minor imperfections on the coated surface. Here's a piece of Bald Cypress with end-grain sealer applied to both ends.
