<h3>Puzzle 03</h3>
<h5>Part 1 (two words)</h5>
I am simple thing, like a yo-yo. I have one moving part, exist now primarily for aesthetics and breaking the monotony. And, while I don't quite resemble a clock, like a yo-yo might (round- face), I would potentially be better suited than it at keeping arbitrary time assuming my load were steady.
<br>
<h5>Part 2 (one word)</h5>
The thing that loads me.
