Lewis Haslett, from Louisville, Kentucky, patented the gas mask on June 12, 1849. It was used to filter dusk from the air. The functions of a gas mask have increased over the years. Today, gas masks are used to protect you from inhaling toxic gases and harmful airborne pollutants. Airborne pollutants can include bacteria, viruses and toxins. Military soldiers or policemen wear gas masks during riots to protect them from tear gas. You may not need protection from toxic gases, but you can still craft a gas mask just for fun.
Things you need
1 piece of A3 size black or olive green cardex (cardboard)
Hat or shirring elastic
Draw the outline of the mask onto the A3 size cardex or cardboard. The outline should be shaped according to the size of your head with a round circular shape that narrows from the jawline to the chin. It looks similar to the shape of a human skull.
Cut out the mask, including the round eye, nose, and mouth holes. Place it onto of the A3 size black cardex and trace the mask onto the cardboard.
Cut out the mask. Place it aside and cut two circles, with a diameter of 4.75 centimetres each, of cellophane and tape them to the back of the eye openings.
Create the nose filter from the black cardex or cardboard. Cut a 30-centimeter by 5.5-centimetre piece of cardex and roll it into a cylinder by overlapping the two ends by three centimetres. Tape the ends together, making sure that the cylinder matches the size of the nose.
Use bubble wrap to make two circles, 5.25 centimetres in diameter. Place pieces of tape around the edges of the bubble wrap circles to secure them to the cylinder. Now, put the bubble wrap circles over the cylinder and attach them together by pressing the tape along the side of the cylinder. Repeat the steps for the other side of the cylinder. The bubble wrap covering should look like goggles.
Attach the cylinder to the nose and mouth hole with the sticky tape on the back of the gas mask.
Cut a 15-centimeter long piece of shirring elastic and tape it to the back of the gas mask on the edge, near each eye hole. The mask is complete.
