In order to further increase the power of portable slingshots, there are two factors that can be optimized. One is the draw weight, the other one is the draw length.

The cannon uses a winch to pull back very strong rubber (a total of 12 full Thera Band Gold bands), and with 2,6 meters the draw length was impressive as well.

But a cannon is not very portable. So a new idea was tested in this video: Four Thera Band Gold bands are attached to a pair of trees, and a new giant slingshot release allows the shooter to clamp in very big ammo (shot put, boule balls, even apples). The slingshot is drawn back simply by walking back. The trigger lever is pressed with both thumbs, then the shot falls.

The contraption weighs about 1,3 kg (just under three lbs) and is probably one of the most dangerous releases ever presented by The Slingshot Channel.
