How to Make a Clay Model of the Planet Venus
- 1). Combine 10 parts white clay with 1 part yellow or beige. Squish the clay between your fingers until the color is nearly uniform with only faint white marbling.
- 2). Roll the clay into a perfect sphere between your palms.
- 3). Insert a wire or toothpick through the center of the model to represent the planet's rotational axis.
- 4). Tilt the model so that the axis is approximately 2.6 degrees left of center when displaying.
