In this blog entry, I use data published by The Slingshot Channel to come up with a simplified formula to predict the depth of penetration of slingshot projectiles in ballistics gelatin.

In this blog entry I consider how slingshots stack up against other other common human powered sports. I have selected a number of sports that involve a human flinging a ball, from golf to the shotput, from soccer to Jai-alai. Slingshots possess the least kinetic energy of all these sports.

Thinner bands shoot slightly faster, especially when they shoot light projectiles, but they don't last as long as thicker bands.

The goal is to impart as much kinetic energy as possible to the projectile in a linear manner directly towards the target without imparting enough spin to affect the flight. However the draw and release is the most critical moment that determines the accuracy of the shot.

A medium sized (8 to 12mm) lead ball travelling at speeds of around 60 to 100m/s will be the most accurate combination and carries sufficient energy to humanely kill any legal game that I can think of.
