Make a Cast of Animal Tracks
The next best thing to spotting wild animals, is spotting their tracks. Making plaster casts of these footprints is an easy way to appreciate and learn more about wild animals.
Instructions
1. Find a clear track in soft mud, wet ground or snow.
2. Gently brush away excess dirt, small stones or leaves. Do not remove debris that is compressed into the track.
3. Make a circular wall around the track using a cardboard or plastic strip. The strip should be approximately 1.5 inches wide. Use a paper clip to hold the strip into a circle. Press the strip into the soil deep enough so the plaster will not run under it.
4. Make your plaster mixture. Mix Plaster of Paris with water according to the package directions. When in doubt, pour a cup of water in your bowl, then gradually add plaster (stirring constantly) until the mixture is thick and creamy like pancake batter.
5. Tap your mixing bowl on the ground, lightly, to remove any bubbles.
6. Pour the plaster into the frame. To protect the track, gently pour the plaster onto the surrounding ground and let it run inside the track-do not pour directly into the track.
7. Let the cast set until it is firm enough to relocate. This usually takes approximately 30 minutes.
8. Remove the cardboard frame carefully, once the plaster is set. Pick up the cast by digging out some of the mud beneath the cast and then lifting it up. Do not pry it up with a stick.
9. Wrap the cast in newspaper to protect it. Allow the cast to dry several days before painting or cleaning it.
