Blowing up a balloon

This week we looked at blowing up a balloon using something other than our breathe. Using our knowledge of the reaction made when we mixed soda and vinegar together we decided to give it a go. Very carefully we put some baking soda in the balloon and then put it over the bottle.

Jamie very carefully tipped the balloon up - so that the baking soda would go into the bottle. Watch the video below.

This is what happened!
