Making a Water Alarm Clock

The most fun you can have watching water drip!

Today we made a water alarm clock. We used a kit I bought on special a while ago, but I was not particularly impressed with the kit as it didn’t include many of the required things. Essentially, water drips from the top of the bottle to the bottom, until the water level in the bottom causes the foil lid to rise to the level of the  paperclips, connecting the circuit and sounding a buzzer. The project was fun and the finished clock will be fun to experiment with. We may try seeing what we can do before the timer goes off, experiment with some different components, and see if we can make the alarm go off sooner or later than it currently does.
