On Thursday Mr Barks taught us how dry ice works. He had a big coke bottle with water in it. He told us that had put a little bit of mentos in bottle. He then added dry ice and water and it started to shoot around all of us on the ground. "Wow!" We all said in amazement.
Mr Barks had stuff that can kill you it is 78.5 Celsius. It is dried ice, if you touch it it can cause lots of damage. He had water and dried ice in the bottle and it made the top blow off. The second one blew the bottom off too. We all were very impressed by Mr Barks experiments. I learnt why it is not safe to play with dry ice because it can give you blisters!
