Two very popular and common objects have the same function, but one has thousands of moving parts, while the other has absolutely no moving parts. What are they?
Eeeeeeeeeeeeeeeezzzzzzzzzzzzzzzzzyyyyyyyyyyyyyyyyy !!!!
An hourglass or else a clock has tells time but hey have a lot of parts working and moving to make it happen.
A sundial, which is older is simpler, and it's oncept allows for no parts to move or make any action because it depends on the sun.
My cousin told me this!!!
