Blow up balloons to 11 centimeters in diameter.
Mix two parts glue with one part warm water in plastic container. Stir until well combined.
Dip strips of newspaper into paste and apply to balloon, one strip at a time. Continue to apply strips until entire balloon is covered. Repeat this process two more times so that you have three layers of papier-mache around your balloon. Let the layers dry overnight.
Pop the balloon with a needle.
Paint the entire papier-mache globe red. Allow to dry.
Add mountains, valleys and volcanoes to the Mars globe using different colored paints, such as black and brown. Use a map of Mars as a reference.
