Yes I have, and can distinctly remember sucking all the flavored juice out of them, leaving nothing but a clear icicle left. The same is true for icies or slushies, which I still do. In this case you have fairly pure ice crystals, intermixed with frozen or liquid water with solute in it. As I had said earlier, once the concentration of solute becomes too great, then the whole mass will end up freezing at a much lower temperature than pure water. The trick it to cool rapidly enough that crystals do not have time to grow significantly before the mass gets below the freezing point of the mixture.
