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! 

Step 1: Doctor...Me?

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.

Step 2: Making the Stethoscope

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

Step 3: OMG!! I Have *TWO* Hearts!

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

Step 4: FINISHED!!

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
