Oxo Ice Cube Tray's sliding lid (pictured, right) allows you to dump out only the cubes you need (even just one). When closed, the lid prevents the ice from absorbing flavors. $4, www.bedbathandbeyond.com.

The slender cylinders of ice formed in the Ice Tubes (pictured, left) can slide into the mouths of most bottled drinks. Run the tray under hot water to release the ice. $4 at Linens ’n Things, www.lnt.com.
