Currents from the Kitchen Lab

So in my hypothesis I thought the potato was definitely going to work the best. We firstly started by grabbing all fo our materials witch were 1 bulb, 1 voltmeter, 2 wires, 1 nail, 1 copper strip and your fruit/vegetable. We then set it up with the copper and the nail in the potato and connected the wires. But after doing this with the potato we realized that not much was happening. We then used a lemon witch worked the best. We then tried to light the bulb witch we could not do. We tried many things but it wouldn’t work.
