The idea is not new, The Slingshot Channel brought a shotgun slingshot as early as April 2010. But since then, a lot has happened – stronger bands and the superior butterfly style allowed much heavier ammo.
In 2010, .177 pellets (4,5mm) were used – now, 10 mm (.40″) and even 12 mm (.47″) steel balls are fired. This required a special formed pouch made from thin Kydex plastics, and also a fully protected “armored” slingshot.
See the scattering of the heavy balls on a white board! In comparison, a 30mm steel ball is fired.
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.
“Invisible” here means: Weapons that can’t be detected with a metal detector, used in airports and government buildings. How dangerous are non metal weapons, really? This video wants to find out.
Airport security is still much more tight than before 9-11. But is it tight enough? Mohammed Atta and his fellow terrorists used box cutters to hijack the planes. Those can’t be brought aboard airplanes anymore, the detectors are (hopefully) too sensitive. But there are still many weapons that
a) are small enough to fit in a pocket without too much bulging
b) won’t be seen by a metal detector
Jörg Sprave tests four non metal knifes (flint, wood, plastic, and ceramics) against a block of ballistic gelatin, “Mythbusters” style. Then, a carbon fibre slingshot is used to fire pebbles into the gelatin.
The end result is clear: More security is needed. All of the tested weapons can seriously harm, even kill, a human beeing. Therefore suitable body scanners and mandatory frisking is a must.
As a bonus, steel and lead balls are also shot at the gelatin, and a samurai sword finishes it off.
On December 30th, 2010, The Slingshot Channel presented a functional “desktop size” slingshot cannon. It fires 8 mm steel balls.
Finally, the model was turned into reality! 10 times bigger than the model, it fires 80 mm steel balls now… with impressive force.
The huge amount of rubber (6 full Thera Band Gold stripes per side, 72 times stronger than “hunterbands” for conventional slingshots) propels a steel boule/petanque ball fast enough so it flies 200 meters (220 yards).
See how it smashes beer barrels and even a car… lots of slow motion is included.
The winch allows insane draw weights. Here, more than 200 kg was employed. In combination with the “barrel length” of 3 meters (10 ft), it achieves firearm like energy levels and the momentum of a giant sledge hammer.
This may be the strongest rubber based weapon presented on youtube ever.!
