Science Fun

This is Room 7 doing their fun science experiments.  

This is an experiment performed by Room 7 students. The experiment was called 'The exploding lunch bag'.

We added vinegar to warm water in a bag, then we added baking soda and sealed the bag shut. We watched as the bag expanded until it exploded.
It was the gas (carbon dioxide)  created by the combined ingredients that caused the bag to explode.  

A great experiement but I think I will stick to putting just my lunch in the bags from now on!
