DIY Tip of the Day: Mini Vacuum Nozzle. It’s tough to vacuum dirt from little nooks and crannies around your house. Concoct this gizmo for tight spots: Poke a long plastic straw through the bottom of a stiff paper cup and run a bit of caulk around the straw. Just plunk the cup on the end of your vacuum hose and the suction will hold it in place. Use a straw with a flexible neck for reaching around curves and corners.
