Step one

Add the ingredients together in a saucepan and mix until all is dissolved in the water (it is okay if some of the sodium alginate has not completely dissolved).

Step three

Pour liquid into tray/ mould and leave to dry for 1-2 days (depending on the temperature and humidity of the surroundings).
