Science: Spud Guns

For science today we did spud guns. It didn't exactly work because the straws kept bending. In my opinion the experiment was really fun because the potato went flying out occasionally. To make the potato shoot you had to push straw through the potato to have a thick rope of potato. After that you had to take the straw out. Then you had to get a narrow blunt stick to push the the potato out. The first time I did it, it didn't work out, but the second time it was flying out, it traveled at least 3 metres. It was really fun!
