[USED STORE DEMO] Diminishing Milk Glasses (multum in Parvo) by Mr. Magic

[PLEASE READ - This item is being sold AS-IS at low wholesale cost because it's a used item.  It works perfectly fine, but we cannot sell it at normal price because it's not a new item.  Item comes in the original manufacturer box with instructions.  It's an amazing deal if you need a Diminishing Liquid routine but don't mind that it was previously used.   Normally $28.75, this store demo unit is only $16.38.]

Four plastic cups of different sizes are displayed on the performer's table. The largest cup is found to contain milk full up to its brink. The performer pours the milk into a smaller size cup, milk does not spill over! Performer then pours the milk into a third further smaller size cup and then into a fourth further smaller size cup, milk does not spill over in either case! Thus to the audience it appears that the original quantity of milk, slowly and magically diminished to a very small quantity... this can also be done in reverse! 

This looks like real magic and is VERY easy to perform.
