K is for KABOOM!

Our letter of the week is K so today we did a K Science Experiment!  We needed vinegar, baking soda and a film canister.  We tipped some vinegar into the canister first. Next we added a little bit of baking soda and really quickly put the lid on.  As the baking soda and vinegar reacted, we could see it starting to bubble inside and then ... KABOOM!  The lid popped off into the air and the mixture squirted out!  Room 5 and 6 thought this was a great experiment to do, I'm sure Mrs Duston could hear the noise we made all the way down in her office!
