For this stethoscope, You require:
- Transparent pipe ( Is used in construction works)
- Medium sized balloon
- Heat the transparent tube using the lighter and fix it on smaller mouth of the funnel.
- Now cut the balloon from the broader part and fix it tightly on the larger mouth of the funnel.
You Are All Set!
