Floral foam so festive that it doesn't have to hide? That's Rainbow Foam from Kent, Ohio-based Oasis Floral Products. Versatile polyurethane Rainbow Foam comes in bricks, cubes, disks and powder, and can be used wet or dry. Six snappy colors — blue, lime green, fuchsia, yellow, pink and ivory — lend themselves to creative arrangements. Standard designs suggested by the manufacturer include the elegant Ice Fountain, which uses a vase full of blue Rainbow Foam cubes, and the bold Block Party, which features three different solid-color blocks in a geometric glass holder. Unique designs inspired by your own imagination include just about anything else. For more information call 800/321-8286, or visit www.oasisfloral.com.
