I developed a Model Rocket entirely from scratch using 3D printed body and home made engine and presented it for expo in my college. It took me 2 months of severe hard work to make it so far. But, despite my hardwork teacher asked "What is this used for?","What's new in this?","Why is your model better than other REGULAR science projects?". I am very disappointed. I ,anaged telling Model Rocketry is the driving force for many children to pursue engineering and sciences but seems like they need a more better sounding quick use case kind of explanation. Anyone please help me. I am really disappointed with the way things turned out despite of my sincere hardwork.
