Hello, we are Sara and Bea and we are going to talk about energy with potatoes. Materials, four potatoes or four pieces of potato, four coins of cooper, four nails, connectors and a light bulb.

00:00:33,310 --> 00:00:55,030
How do you do it? In the potato we put one nail and one copper coin. And then we do that four times. When it's already done, we put the connectors with a nail and a coin so the materials can connect.

00:00:55,030 --> 00:01:12,030
When it's all done, it is going to produce energy because each potato is going to work as a butter.

00:01:16,030 --> 00:01:17,030
One second.

5
00:01:22,579 --> 00:01:23,579
Yes.

6
00:01:23,579 --> 00:01:25,579
And the light turns on.
