The internet was truly an amazing thing, and Amaya tended to use it to find interesting new ideas to try in her shop...and, well, her shop class. So when a bit of random scrolling and reading lead her all the way over to an article about ancient Greek alarm clocks, she immediately knew she had to do something with that.

Or, well, maybe make her class do something with it!

"Today," she said, "I've decided we're going to dive into a little project focused around a clepsydra, or water clock. Well, technically, it translates into 'water thief, but these devices were basically a way to have an alarm clock when you didn't have actual mechanical time pieces or phones you could conveniently set to a specific time. With these devises, time is measured by the flow of water from one vessel to the next, much like sand in an hourglass, but an alarm version of a clepsydra would involve some other mechanical element that will create a signal when the water reaches a certain point.

"I'll go over some examples and break down various aspects of how they work, and then the challenge is for you to try and recreate a current model or experiment with your own form and structure. But the key elements need to be present: it needs to use the passing of water to create a way of marking the passage of time, and there must be some sort of alert or alarm system to inform people of when that time reaches a certain point. Do we have any questions right out the gate?"
