As we were brainstorming the outline of our project, our group considered the possibility of basing our project on solar panels. However, after discussing the purpose of the experiment and how it would relate to sustainability, we realized that it would be too complicated to explain, as all of us had minimal knowledge of the matter.

Eventually, Gabriel mentioned the potato experiment, which he found online. We began researching it, and upon seeing the ingredients, we started working. At first, we thought it would be a good idea to merely test different fruits to check the voltage of each fruit by connecting them to NXT and opening the Shake generator’s code. However, as we were experimenting, someone thought that it would be a good idea to try lighting an LED bulb.

The first few tries were a failure. We began by connecting an apple and a banana to an LED bulb. As you can imagine, nothing happened. Therefore, we began analyzing what we needed to make it work, and after realizing that the LED bulb required 3.5 V, and the two fruits together only generated about 1.6 V, we acquired two more bananas and connected them in a circuit.

To make the circuit, we acquired copper and galvanized nails, and we put one of each nail in each fruit. We connected the fruits with alligator clips from the copper nails to the galvanized nails, and then to the LED bulb. The bulb finally lighted up, but the color was very dimmed, so to make it brighter, we noticed we needed to either add one more fruit or vegetable, or use apples, oranges, and limes which are better conductors thanks to the high content of acidity and water.
