Today in science, we did a test for potato guns. The things we used were McDonald straws, a skewer, a potato, and paper to record your results. The first thing you need to do is put some potato in the by stabbing your straw in the potato. You'll need a bit of potato in one end. Secondly, you need to put some potato in the other end. Once you've done that, you need to slowly push the skewer in the straw in any end. Make sure you use the blunt side of the skewer and not the sharp side because you could pick up the potato. The way you know that you've done it is when you see it fly pretty far. And maybe it wouldn't work for others because you either used the wrong side or maybe you pushed the skewer in too fast. Or maybe because it wasn't airtight. This experiment didn't work for everyone but it was fun.
