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 theย  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.


Love those old books…

We borrowed a book from the library called Magnets, Bulbs and Batteries. In it was a picture of a model lighthouse. LE wanted to make one…

Yes, it works ๐Ÿ™‚ It has whale marks in the water, of course, and rocks around the lighthouse. We are going to replace the red bulb holder with a smaller one when we buy a globe to go in it! And it will be painted once it’s dry.

And A? He was drawing, and poking holes in clay with pencils. ๐Ÿ™‚
