This technical note describes the spontaneous liquid uplift in biliquid capillary siphons. It was found that, in general, liquids that have a low surface tension to wet the wick material and a low viscosity ( methanol, etc.) could be spontaneously uplifted to liquids with a high surface tension ( water, etc.) or high viscosity ( glycerin, etc.) through a wick configured in a siphon fashion. An interpretation of the results using the liquid capillary rise equations is given.
