In the world of weapons there are modern and classic firearms. Our Inventor focus today is on the guns of a time gone by when black powder guns were all that were used (think Daniel Boone here!). Inventor Tim Friis from Minnesota joins us on this weeks edition of My Cool Inventions Radio and shares with us his invention..the Kalver Black Powder Cleaning System! Cool Inventions, Cool Gadgets...That's what this show is all about!
