This builder created a pretty amazing machinegun/chaingun that shoots rubberbands. The gun is built completely out of LEGO. It supposedly fires 11 rounds per second.
It's a video connected with the song آپ can hear while watching, and was made to tell us what it's all about in this song. The song is 'Jozin z bazin' سے طرف کی Ivan Mladek - a comedian from Czech Republic. enjoy :)
