This potion is an ancient potion that isn't made by wizards, but natural. The potion is grown on an Invisibilus Tree which makes the potion hard to find because the tree is invisible. The potion is made in a cauldron and can't leave it, and holds the potion which makes the drinker invisible for a limited amount of time. This potion was given to Thomas Joshman on December 25, 2011 and disguised as a toy digger.
