New videos coming in March!! We built the world's largest Nerf Gun with Mark Rober and obliterated some watermelons with it! We also compared the black powder cannon to the existing pneumatic air system. Check out Mark's channel to see this thing shoot oversized darts! https://www.youtube.com/watch?v=57MKxz4pJKE For instructions, downloads, detailed write ups (may take a few days) http://www.eclectical-engineering.com Facebook: https://www.facebook.com/EclecticalEngineering Please like and subscribe!
