The Recipe was "Mandrake Restorative Draught". The "Mandrake Root" is baking soda, the "Phoenix Tears" is vinegar and the "Dandelion Root" is baking soda (dyed yellow). |
The students were asked to add a small amount of "Dandelion Root" to the jar. |
The potion became very fizzy. |
To that they added water. |
