This year the third graders leared about simple machines and each student was supposed to come up wiht a way to smash a grape. This is Emily and her grape smasher. She placed a grape on one end of a tube and then pulled a pulley, the grape rolled through the tube and landed in a small bowl. Then she used another pulley to pull a rock up and then let it fall. The rock landed in the bowl and smashed the grape. She had a lot of fun creating her grape smasher.

Cool grape smasher. You should try it on your dad.
The picture of the kids with Grandma was good.
Good design Emily!
