Each student should have picked a planet or other heavenly body to create a model of. The scale of the planets will have been determined previously. Have the students tear strips of newspaper for their models. Get all other materials ready. Clear tables off and cover with newspapers.
Students can wear old shirts so they wont get dirty.
Inflate to the predetermined size and knot. Dip the newspaper strips in the starch one by one and apply five full layers. Let the balloons dry over night. Once the balloons are dry snip of the knot in the balloon. Then run a thin wire through one end and bring it out the other.
