Cory made a very cool grapple hook at Extended Day yesterday (with some help from Diana, who dreamed up using pipe cleaners for flexible strength - nice!). Today he was grapple-hooking the IKEA shelving unit I'd just built - and quite successfully too. :-)
Unfortunately he next tried tossing the hook up onto the roof (against Mom's advice) and of course, it stuck in the gutter. Sometimes moms really *do* know best.
