Difficulties Putting It into Practice – Air Guiro

 Instructions on how to build the “Air-guiro’’:

Take a thick A4 piece of paper. Experiment with different thickness of paper to check the best possible result.

Draw 8 parallel rectangles around the middle of the paper. Each rectangle should be approximately 1 cm wide and 4 cms high. The rectangles should be separated by approximately 2 cm. Leave around 3.5 cms to each margin in order to be able to hold the paper with easiness.  

Cut the upper excess of the paper in order to keep it away from the nose and eyes while blowing. Leave approximately 2 cm between the edge of the cut paper and the drawn rectangles.

Make the holes by cutting the drawn rectangles with a paper cutter.
