What happens when a NERF dart breaks the SPEED OF SOUND?

The video tutorial explores the creation and testing of a supersonic Nerf cannon. The project involves upgrading a Nerf gun to achieve higher speeds using helium and a vacuum system. The video details the building process, testing phases, and challenges faced, such as the Nerf dart exploding at high speeds. It also delves into the physics of projectile speed, explaining the limitations and potential solutions. Advanced testing includes using Schlieren imaging to visualize shockwaves and conducting various experiments to enhance the Nerf cannon's performance.

What is the theoretical limit for projectile speed according to the creator's research?

What was the outcome of the ultimate challenge involving the half-inch pinboard?

How did the creator use Schlieren imaging in their experiments?
