How to blow up a balloon without a single puff! 1

In Science this week, we have explored the differences between reversible and irreversible, physical and chemical changes. We have tried out a range of activities to investigate how materials change state and how they create new products. We made our own butter (which we were able to taste on some crackers!), created our own casein plastic decorations using just milk and vinegar and even had a go at blowing up a balloon by using vinegar and bicarbonate of soda to create carbon dioxide! Check out the pictures below.
