Ninth Grade had two different projects. One of them was very creative...their own invention.

During their presentation they asked what happens when you are filling your Pila?

You would have to have a pila to know the answer...but the answer is...that you have to keep going and checking on it or you will run it over with water.....So they created an invention to notify you when your pila is full of water.

So Ronny began filling the bucket.....

....and as the bucket filled with water, the bulb floated up and made the pole turn on the light switch.

Their original idea was to make it with a bell, but they didn't have enough money for the bell, so they made it with a light instead....

How ingenious!!! We all want one for our pilas!
