## Introduction

School is more than just reading books and doing homework, as we all know. We all know that there are practicals and experiments as well in the school’s curriculum. Especially when we talk about subjects like science, practicals and projects are highly common. One of the topics that are assigned to students is How to make a pulley door system for a science project.

It is quite common to face trouble while working on a science project. Are you not able to assist your child well in his or her science project? If your answer is yes, we’ve put together a step-by-step tutorial for a pulley door system that is generally assigned to students as their science projects.

It can be quite helpful to make the pulley door system as it is a good way to learn more about how it functions. It enables you to understand the mechanism of the pulley door system in an interesting and fun way.
