Red Cabbage Indicator

 Its that time of year to cut up the red cabbage and make red cabbage indicator. Fun but smelly.

Blend a leaf of red cabbage with 100 ml distilled water. Filter (cheese cloth recommended). The resulting solution displays pretty much a full range of colours from pH 1 to14. Some people recommend boiling the cabbage but it is not necessary
