What will happen to the gummy bear?

This week, we started our science work by developing our skills in observing over time.  We measured carefully and observed gummy bears in different liquids after 3 hours, 24 hours and 48 hours.

We used water, salt water, sprite and vinegar. Our liquids were all at room temperature.  After 24 hours the gummy bears looked like this.

Can you work out which liquid the gummy bears have been in?  How do you know?
