Hand crank Technic Competition Cannon Revolver Machine Gun.
About this creation
Technic Competition Cannon carousel - CBS Elementary Mousetrap Contraption
This contraption is inspired a Rube Goldberg like contraption found in the opening
title scene to the cBS TV series"Elementary" created by the Production studio Prologue,
called "Mousetrap." In the opening title sequence of "Mousetrap," four revolvers in a contraption created by Rolling Ball sculptures are strapped onto a carousel which rotates 90 degrees at a time - the first time the carousel rotates 90 degrees nothing happens but the second time the carousel rotates 90 degrees a revolver fires off a round because there is a string tied to the trigger of one of the revolvers. My contraption replaces the 4 revolvers with 4 Lego Competition Cannons and instead of a string there is a firing latch on the top of the carousel.
