- The circle should also be placed over the general area of your face. To make sure that it is located in the right spot, place the bag over your head and have a second person trace the circle onto the bag directly over your face.
- You should also consider cutting a half-circle into the bottom left and right sides of the bag. Doing so is not strictly necessary, but it may help the bag sit on your shoulders more comfortably.
- Repeat this step with the second oatmeal box lid, as well.
- You can leave the lids on or take them off during this step. Note, however, that you will need to temporarily remove the the lids when you cut these circles out.
- You might need to use the point of a nail or the sharp tip of your scissors to punch a starting hole into the lid somewhere along the outline of the circle. After creating a starting hole, slide the scissors into this hole and cut around the circle as you usually would.
- Make sure that the lidded sides of the oatmeal boxes face up.
- The bottom of each oatmeal box should extend below the bottom of the paper bag.
- Repeat this step with the second paper towel tube and the second oatmeal box.
- These cardboard tubes should mimic the appearance of oxygen tank hoses, and the oatmeal boxes should mimic the appearance of oxygen tanks.
- Also consider decorating the helmet with lightweight embellishments, like stickers or aluminum foil shapes.
Wear your space helmet. At this point, your space helmet should be ready to wear. Slip the bag onto your head with the hole in the front and the oatmeal boxes are in the back.
Method 2Papier Mache Helmet
Inflate the balloon. Blow up a standard balloon so that its final size is a little bigger than the size of your head. Tie the end of the balloon into a tight knot.
- Tear the newspaper into strips. Take five large sheets of newspaper and tear them into 2 to 3 inch (5 to 7.6 cm) wide strips.
- If you have not done so already, prepare a papier mache paste now. Combine 1 Tbsp (15 ml) of corn flour with 1 qt (1 L) of boiling water until a paste forms.
- Adhere the newspaper strips to the balloon. Dip one strip into the papier mache paste and lay it flat across the surface of the balloon. Repeat with your other strips, laying them onto the balloon vertically and horizontally.
- When done, the balloon should be covered by roughly five coats of newspaper.
- Cover the entire balloon except for a small patch near the knotted end. You will need this space to remain open so that you can get the balloon out of the structure later.
- Let dry. Set the papier mache structure aside in a dry, draft free area. Allow it to dry undisturbed for about 24 hours, or until the surface is still and completely dry to the touch.
- The paste needs to be completely dry before you continue past this step.
- Your climate will change the rate at which the paste dries. If you live in dry conditions, the paste will dry quicker. If you live in notably humid conditions, the paste might need more than 24 hours to dry.
Remove the balloon. Use a pin to pop the balloon through the gap you left at the base of the papier mache. After popping the balloon, carefully pull it out through the hole.
- Cut the papier mache structure into the shape of a helmet. Use scissors to cut off the bottom of the structure, then cut away a section for your face to show through.
- Work from the bottom or open end of the structure. Cut off enough of the bottom for your neck and head to fit through.
- Still working from the bottom end, cut a rectangle in the front of the structure. This rectangle should be as wide as the distance between the outer corners of your eyes. It should be about as long as the distance between the bottom of your forehead and your chin.
- Paint the helmet. Use paint and a paintbrush to decorate the helmet however you desire. You could also decorate the helmet with foil shapes or space-themed stickers.
- Note that you can also attach antennae. Poke two small holes in the top of your helmet—one near the left side and the other near the right side. Slide a pipe cleaner into each hole, and tape the end of the pipe cleaner into the inside of the helmet to secure it. You can twist a bead to the top of each pipe cleaner to complete the antenna look.
Wear your new space helmet. Once the helmet has been decorated to your liking, it should be ready to wear.
