Potion of Growth

The red liquid in this potion's liquid continuously expands from a tiny bead to color the clear liquid around it and then contracts. Shaking the bottle will move the center point of this process, but will fail to interrupt it. 
Upon drinking this potion, the user gains the "Enlarge" effect of the "Enlarge/Reduce" spell for 1d4 hours.
