Potato Gun Experiment

Today for science we tried to make potato guns. The things you need is strong straws, a potato and skewers.  The first step is to get the  straw then jab it in the potato and twist the straw while it's in the potato. Then you pull it out and hopefully you get some potato in the straw. After you do that you have to do it to the other side. Once you have done that you get the skewer and stick the blunt side of the skewer into one end of the straw and keep pushing the skewer to the other end the straw. If you did it correctly some of the potato should go flying. One of the reasons why it didn't work for some people is because the straw wasn't airtight. I was sad because my straw broke so I couldn't do it.
