Mister Ken and I went to see a grandfather clock, it needed to be set up correctly in order to tell the time accurately and be in beat. This means that the pendulum has an equal swing on both sides. This creates the tick tock and ensures that the clock will go, if it is not in beat it will not go.
This clock had been made a little later than me. Mister Ken put the clock in beat and it is now accurately telling the time. As part of this the pendulum was adjusted.
The maker of the clock was at the cutting edge of technology at that time. He was interested in electricity.Have a look at this link to find out more.
