Spud Guns

In class we made spud guns. Spud guns are straws that have potato in them. We firstly had to stab one side of the straw into the potato and then we did the other side. We then got a skewer and pushed one side with the potato in it. It usually shoots the other bit of potato out but ours didn't work. We tried to get it to work but the potato didn't come out. It was fun to try this experiment. Next time we try I hope it works.
