Science road show

On Tuesday the 13th of March the Ngaumu class went to the Science Road Show. My favourite part was when we learned about Liquid Nitrogen. It was really cool when one of the exhibitors put some gloves on and got some Parsley and dipped it in Liquid Nitrogen. He had the gloves on because liquid nitrogen is so cold that it will burn your skin. When he brought the parsley out it had ice on it and then he squeezed it and it crumpled all over the table. Another favourite was the Elephant tooth paste. That was cool too because when the exhibitor put two cemicals together , this pink foamy stuff came out like tooth paste and it was massive. One of the men did this thing where he put dried ice in cold water and then it made clouds of cold air. It was a really fun day and I had loads of fun and I learnt a lot of new science things..
