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
