The wire Bit has a flexible wire running between its 2 bitSnaps. This allows you to place your Bits farther apart from each other turn corners and make connections that can twist turn and spin. Try it whenever you need to break up your chain of Bits like when you need to put a light at the top of a model building!
HOW IT WORKS
The wire doesn’t change the signal in any way – it just carries it over from one Bit to another.
