I love watching The Slingshot Channel. There is just something alluring to the completely affable Joerg Sprave and his various rubber-powered inventions. Until now, he has not show you how something was built, instead only showing various objects thrown at high-speed.
In a break from his normal videos, Joerg breaks-down the manufacture of a simple (but entirely effective) sling/cross bow. Might be a touch more than $5.00 in parts, but with common tools, you too can be slinging slingshot.
