Another jar of potion with fizzy bubble things or use without? nothing fancy

//Hi people just a quick note ive noticed if you use the pics and make it animated with the bubbles and slice them up multiple in Unity5 you get a wonky animation, so you have to SLICE them up individually to the same size as potion_4 with the highest bubbles then you get a smooth animation with the bubbles rising up. Hope this helps and makes sense
