The 5 gram packet of crystal soil expands to fill a volume of over 800ml when soaked in water for 10 hours. People are amazed by the huge expansion of the water crystals and often ask about the volume produced by a single 5 gram (0.18 ounces) packet so it is illustrated here in a measuring jug. The result can be used as a guide for selecting the number of packets needed to decorate a flower vase or candle holder etc. Measure the volume of the vase and divide by 800ml (0.74 quarts) to give the number of packets required. Note that 800ml is a conservative estimate and the actual volume may vary a little between lots.
