Science with Mr Naffa

We were treated to a special visitor to our team during Science week - a real scientist! Mr Naffa treated us to some amazing science experiments with dry ice. The scientific name for this is liquid nitrogen. It freezes at -200 degrees!! Brrrr that's cold! He showed us how quickly if could turn a squishy marshmallow into a solid  marshmallow. (They still tasted yum!)





We then went outside and Mr Naffa made elephant toothpaste. It made us all go oooh and aaah
