A cool video has emerged of YouTuber JK Brickworks building a machine capable of beating one of his previous creations - the "Ultimate LEGO Machine".
In the footage, shot last week in Ottawa, Canada, JK Brickworks builds a hand made of LEGO in order to turn off his "useless machine".
Three years ago he showcased the Ultimate LEGO Machine in a video that accumulated over ten million views.
The machine has a switch which the user pushes forward before a robotic arm immediately pushes it back.
His two inventions can be seen entering a long-lasting battle until the original Ultimate LEGO Machine breaks.
