After trying the cabbage indicator at school,
i decided to make my own indicator at home...
and yes, i used SPINACH!!!
well...
This was how it went...
the square bottle is the control...
the other has been added with soap...
well, i don't know if it changed colour because of the soap's yellow colour...
Next...
for this one i added lemon juice...
not much of colour contrast...
i'm not sure if this is counted as pass or fail... xPP
watch the cabbage indicator below~
guess that's all~
E.T.
