Make a chocolate river for a school project?
My sister is making a Charlie and the Chocolate Factory project for school, and I want to make a real flowing chocolate river. I understand it would be very difficult to do this with real chocolate, so I was thinking I could use chocolate milk. Anyone have any idea on how I could do this? Maybe something with a little tank underneath and a water pump in it or something. The box we are creating this is is a plastic shoebox, but only half of it can be used for the river.
Any help is appreciated!
