- Paper Coffee Filters
- Washable Markers
- Spray Bottle with Water
- Using washable marker pens in blues and greens, color your coffee filter with continents and oceans. Although it can be fun to think about the shapes of the Earth’s real continents and try to draw them accurately, this isn’t at all important. You just want to create a “blue-green marble,” like our planet as seen from outer space.
- When you are satisfied with your continents and oceans, lay your coffee filter down flat on your table surface and spray it lightly with water from the spray bottle. The ink will begin to run together and spread, like a watercolor painting.
- Leave your wet earth on the table top to dry. We did ours outside and they were dry within 20 minutes or so. As soon as your earths are dry, they can be taped up in a window. If they are too wrinkly for your taste, gently iron them on medium heat (and without any water spray or steam).
