Orbitz is a non-carbonated soft drink, within which flavoured gel spheres (orbs) are suspended. It comes in five different flavours and colours; in the current experiments, we have concentrated on orange, red, white and yellow orbitz, particularly the first two. Interestingly, in what must have been a rogue batch of red Orbitz, the orbs readily settled. In the present communication, we address two related questions. First, why do the orbs generally remain in suspension? Is it the matched densities of the orbs and the surrounding liquid or is it the distinctive rheology of the liquid? We show that, although both may be involved, rheology is certainly the dominant influence. Secondly, why did the orbs settle readily in the rogue red sample? We again show that (imperfect) rheology is responsible for the malfunction.
