For a project we are creating large tubes that have to look as if they are filled with Coca Cola and Fanta liquid. We want to run accidental air bubbles through the liquid. The tubes are meant as exterior props on a Mobile Vending Machine. We don't want to use real Coke or water, due to shelf life etc.
What would you guys suggest, as an acceptable resemblance material?? A bit thicker viscosity would not be a problem...
Any help would be appreciated
