Today on the last day of school Mrs K thought we would have a fun day. We already had a bottle, vinegar and baking soda. With the bottle there was a tube that held baking soda. In the bottle there was the vinegar. We had two attempts, they both failed. It was probably because we didn’t shake the bottle enough. Third time lucky? Yes third time is lucky. Mrs K held the bottle and shook it violently. When she let go of the stopper it burst all over Mrs K. That was the best part!
