Stick-Lets are thick pieces of silicone with holes cut out. That’s it. But they’re all you need to build better backyard forts. They’re simple joiners that you slide them over differently-sized sticks so you can easily maintain structural integrity. The various components in a bag (each contains 18) are stretchy, but strong enough to stay put around large branches, connect with hanging limbs, and basically inspire kids to build sculptures, bows and arrows, functional teepees, or a replica Blair Witch totem.
