The experiment from this website has been tried and works well:

The experiment involves identifying how much Ribena needs to be diluted before it becomes isotonic to potato cubes.

Students then do their own investigation with a fluid of their own choice (i.e., lemonade, orange juice, etc.) to determine the correct dilution to give to a dehydrated child (i.e., with the same solute concentration as the potatoes).
