On Thursday 26 April Room 6 got to look at ice balloons. I think that the water that Brownie put in the balloon made bubbles and when Brownie put it in the freezer the bubbles froze because the air was trapped. We saw the ice balloon crackle when Emma put salt on the ice balloon and the salt was slowing the ice balloon down from melting. Then Michael put green food colouring on the other ice balloon. Someone suggested we put salt on the ice balloon with the food colouring and the ice balloon crackled . We were really amazed because the food colouring melted into the ice. The salt turned green because of the food colouring.
