Today Mr Tierney and Hassan made a periscope. It was quite fun. Periscope's are used in the armies . They are used on submarines to see above the water. They made it with two mirrors and a cylinder made of carboard. We looked through it and it looked like there was another hole on the other side of the bottom,but what we were seeing was over our heads.We were lifting a crayon and we saw it and John got a fright. Everybody got to see the periscope and Matthew got a fright too. It was cool to look out it.
