Exploding Bags

This week to inspire out writing in Ako 3, students exploded some snaplock bags. To do this we put food colouring and vinegar in the bottom of the bag and then pegged that close. We then put baking soda on top and sealed the bag. Once we let the peg go the baking soda hit the vinegar and then began foaming. The students had an awesome time and got some descriptive writing from the experience.
