1. Start seedlings

Cut off the lid, fill each cup with potting soil, and plant some seeds. Once the seedlings sprout, cut each cup from the tray and plant it—cup and all.

2. Muffle the band

This Old House technical editor (and former rock-star wannabe) Mark Powers once nailed egg cartons to his apartment walls and ceiling to dampen sound while he was recording.

3. Feed birds

Trim off the lid, thread string through holes in each corner of the tray, fill the cups halfway with birdseed, and hang in a tree.

4. Fire the grill

Melt candle scraps in a double boiler, then fill each cup halfway with sawdust. Carefully ladle the wax over the sawdust, and let it cool. Each cup can now serve as a fire starter—just light the edge.

5. Cushion ornaments

The cartons are ideal for separating small, fragile Christmas ornaments for storage.

6. Organize fasteners

Use your cartons as repositories for screws and bolts removed during appliance or other household repairs. Numbering the cups ensures proper reassembly.

7. Round up tiny spare lights

Those stray 4—watt night—lights and holiday bulbs won’t last long rat­tling around in a drawer. An egg carton’s cups make for ideal storage. For this use, keep the lid.

8. Ship cheaply

Being stiff but lightweight makes egg cartons excellent replacements for Styrofoam packing peanuts.

9. Manage a farm

Torn up, egg cartons are a great food source in worm farms. If the soil mix is too moist, add dry carton pieces. Too dry? Dunk them in water first.

10. Cool a drink

Now, he wouldn’t try this with paper cartons, but This Old House general contractor Tom SIlva says that in a pinch, the foam variety doubles as a great makeshift ice cube tray when you’re stocking up for guests.
