When you go to the doctor , he often uses on instrument to listen to your heart and lungs . this gadget the doctor uses is a binaural stethoscope . in this paragraph I tell you how you make a simple stethoscope .
I used 4 Materials to do it , these tools contain cardboard tube from a used roll of paper towels, a piece of aluminum foil , duct tape and Scissors .
I followed 4 steps to do it . first , wrap aluminum foil over one end of the Cardboard tube that came from a used roll of paper towels. Then, used Scissors to neatly cut the ends of the foil . so your "stethoscope " looks better . now wrap duct tape over the ends , of the foil .
I didn't face any problem when I doing it
