Aug. 7 was National Lighthouse Day, commemorating the date more than 200 years ago when Congress approved an act to establish lighthouses, beacons, buoys and public piers to protect mariners from the perils of coastlines.
To commemorate the American lighthouse, I made this one with instructions I got at http://familyfun.go.com/crafts/lighthouse-in-a-bottle-666011/ on the Web, where you also can find a video of the project.
1 1/2-liter sport water bottle
White craft glue
Red acrylic paint
Red and black tape
White craft foam
Clear packing tape
Ask an adult to cut the bottle in half with a craft knife. Glue aluminum foil inside the cone-shaped portion of the top half (this creates a reflective dome), then use red acrylic paint to coat the outside of the foil-lined section.
When the paint is dry, apply 3-inch vertical strips of black tape, spaced evenly, around the unpainted portion of the bottle top.
Pack a baseball-size ball of modeling clay in the bottom half of the bottle. Stand a flashlight upright in the clay and press down to secure it in place. Cut a notch down from the bottle's edge to allow access to the flashlight's switch.
Wrap an 111/2-by-10-inch sheet of white craft foam around the bottom half of the bottle (the foam will extend about 4 inches above the bottle) and note approximately where the flashlight switch opening is. Remove the foam and cut out a piece for the flashlight switch opening. Re-wrap the foam around the bottle and secure the overlapping ends with clear packing tape.
Fit the cut edge of the bottle top just inside the foam sleeve and securely tape the foam to the bottle with colored tape.
Wrap the lighthouse with a spiral of red tape to decorate.
