Every child's school career includes the making of a shoebox diorama. These dioramas generally include animals, trees, clouds and a body of water. Make a simple pool or lake using fake water you create with several types of craft items that don't cost much and are easy for kids to help out with. The diorama can be an educational project that you and your child will both enjoy.
Follow the directions on a package of blue gelatin dessert, and use that as fake water. You will have to put the gelatin into a container so it won't leak into the rest of the diorama. If you are using something to serve as a waterproof liner for the miniature body of water, you can pour the gelatin directly into the diorama.
Cut a piece of blue construction paper to fit the area where you want your body of water. Place blue cling film over the construction paper to add shine and a watery appearance. Ripple the cling film a bit to make it look more realistic.
Purchase a liquid water simulant made especially for craft projects at a craft or hobby shop. Pour it into the diorama or use a little bit on top of paper to add a more realistic effect. Allow the liquid to dry completely for best results.
