Potato Experiment

Today we did an experiment using potatoes. It's called a potato gun. We used straws, skewers and of course potato's. You poke the straw into the potato in to both the sides of the straw. Then you use the skewer to poke one of the potato's out and that makes the other bit of potato shoot out. It's all because of the air pressure. That's how it's supposed to work, but our guns didn't work. My gun didn't work because it wasn't air tight.  😞
