Vinegar+Baking Soda Experiments

On Thursday the 14th of November room 12 did some cool experiments with Mrs Demchy. First we got a glass bottle and filled it up with vinegar. Then we filled a balloon with baking soda and carefully put it on the bottle. Mrs D shook the bottle and all the carbon dioxide created blew up the balloon. For the second experiment we got two plastic bags. we filled one up with vinegar an another with baking soda. in the second bag where we put the baking soda we cut a hole in the corner so the baking soda could escape. We shook the bag and after a while the bag popped and squirted all over everyone! For the third experiment We got Mr Peachy to nail a few holes in the cap of a bottle. Next we filled a bottle 3/4 full with vinegar and a bag full of baking soda. We dropped the bag in the bottle and screwed the cap on. Mrs D shook it and it squirted all over us.
