Let your little budding astronaut explore the universe from the playroom in a homemade rocket ship. Build the rocket ship from a large cardboard box and have the child decorate the box with all of the pictures he relates to a trip to outer space. Decorate the playroom with glow-in-the-dark stars, and turn off the lights to make pretend play even more adventurous.
Place the long, large box on your working surface. Draw a triangle on the top flaps of one, short open end. Draw the triangle from the outside edges of the box to a point at the end of the flap. Cut off the excess cardboard beyond the triangle and save these pieces for later.
Fold the triangle flaps inward and use duct tape to hold the pointed ends together. Stand the box upright on the opposite short end.
Draw a large rectangle door on one long side of the cardboard box. Make the rectangle large enough for the child to climb into and out of the rocket ship. Cut one long side and the two short sides of the rectangle. Fold the cardboard along the remaining side to make a door that opens and closes.
Arrange the excess pieces of cardboard around the base of the rocket ship to make the "fins." Use duct tape to attach the fins.
Use a paintbrush to paint the entire cardboard rocket ship with a white or metallic silver paint. Alternatively, spray paint the box outdoors or in a well-vented area.
Decorate the rocket ship with markers. Make stars, planets and other space pictures.
