Thursday Experiments

One of our experiments Rm 12 did on Thursday with Mrs Demchy was trying to blow up a balloon using CO2 gas made by baking soda and vinegar.  First of all we got a balloon and a bottle with a small neck so we could put the neck of the balloon around it.  We filled the balloon with baking soda and had the vinegar in the bottle.   Next we went outside and put it together.  It only blew up a little bit but then Mrs Demchy tipped the vinegar into the balloon and it expanded to a full sized balloon.  Most people got to touch it and see how firm or soft it was.  We weren't aloud to squeeze it to much just in case it popped.  We went inside and talked about it.  This experiment was one of 3 successful experiments.
