Sebastian Dick said this LEGO chaingun was the biggest project he’s ever tried. It has eight barrels and a 64-shot capacity.
The motor driven barrels start winding up to speed at the flick of a switch on the handle. Pulling the trigger unleashes a stream of rubber bands, deluging the target. The fire rate is high enough that at least half a dozen bands are in the air at any one time – the gun appears to fire a single very long chain of them. It’s as much like using a hose pipe as firing a rubber band gun. It also sounds fantastic because each mechanism makes a distinct click as it discharges a rubber band.
