How to Make a Last Minute Stethoscope

Well I'd just been invited to a Dress up party on the last minute and i'd just watched a Doctor.Who episode and i was like hmm what would the doctor do(i was in a Doctor.Who trance) and i thought he'd make a disguise for himself and since his name is the Doctor he'd make a doctor costume! and i already had most of the stuff for the doctor costume so i just made a stethoscope and here is the finished product! 

Ok so firstly you need the things to make it these thing are:
A pair of ear *Plugs*
A Page of some sort of cardboard paper stuff (sorry i don't know the real name)
Scissors
and a pen/pencil.

Firstly you need to trace a circle on the cardboard paper stuff and cut it out.

Then puncture a small hole into he circle and insert the end of the ear plugs into the Circle.  

You are now an official Doctor (Don't try surgery it doesn't end well) 

This is just a Step full of all the pictures
