Freya’s This Is Science – The Bicarbonate Balloon


We’re going to do an experiment. You need a big bottle… …and some vinegar… …and a balloon… … and some bicarbonate of soda. We’re going to put some bicarbonate of soda inside the balloon. We’ve got a funnel to make it easier. Put the funnel inside the balloon. There… *whispers* Ready Ready Ready! Tip some bicarbonate of soda inside the balloon. It’s full of bicarbonate of soda. Next we put the vinegar in the bottle. We can use the funnel. *I might need to stand* *It’s quite heavy* *It is quite stinky… I just smelled it!* *It was quite stinky wasn’t it?* Get your grown-up to put the balloon on the bottle. Don’t tip the bicarbonate of soda in yet. *giggling* The chemical reaction made a gas. The gas blew up the balloon. *can you do it?* Thank you for watching my video. Please subscribe! Bye! *singing a made up song* “What are we going to do today?…. “….It’s going to be an experiment!”
