Building a diorama with a mini fake pond is an interesting project for the modeler and crafter. The addition of a water feature adds to the depth and beauty of your diorama. By avoiding the use of real water, you can set the pond in the background or right in front without fear of messy spills or your puppy drinking from your pond.
Spray the pie pan with stone-texture spray paint. Spray in several light coats to avoid sagging or dripping paint. Allow it to dry completely.
Glue the mirror to the bottom of the pie plate using a hot glue gun. Allow it to dry, then apply hot glue to the flat bottoms of the marbles and attach to the mirror in a rippling pattern. Leave the outer edges uneven to simulate a natural pond.
Attach pebbles or aquarium gravel around the edges of the pond, using the hot glue gun. Work your way outward to the edge of the pie plate.
Place your fake pond on a flat surface where it can stay undisturbed for at least 48 hours.
Mix the clear resin with the activator in a plastic mixing cup according to the package directions. Stir with a craft stick. Pour the resin over the mirror and marbles until the marbles are barely covered. Allow it to dry, then add a second, thin coat of resin swirled with a blue or blue-green tint. Allow it to dry, then add a third clear or barely tinted layer of resin.
Spray the pond with resin spray for a clear finish coat. Allow it to dry completely; this should take at least 48 hours. Depending on environmental conditions, it may take two weeks to completely dry.
Work in thin layers; the resin will cure faster and with fewer bubbles. Casting resin kits are available at arts and crafts stores or online. Inexpensive mirrors are available at discount and dollar stores. Tiny objects are often embedded in the layers of resin for a realistic effect. Use a pizza pan or baking tray to make a larger pond and diorama. Hobby stores have miniature trees and houses intended for railroad hobbyists' train dioramas.
Work outside in a sheltered area or in a well-ventilated garage. The fumes are extremely strong. Wear safety glasses and gloves. Drying time varies by the thickness of the resin, humidity and temperature. Allow extra drying time to ensure the project is completed in a timely way. Not for use by children.
