A LOT in a LITTLE! And this is the REVERSIBLE version!


This centuries-old classic trick was originally named MULTUM IN PARVO for the Latin phrase meaning "much in little" or "a great amount in a small space".
And that is exactly the effect!
But it is an IMPROVEMENT over the original effect!
With MORE MILK, you can not only fill a larger glass from a smaller one, but you can REVERSE it and pour the larger glass into the smaller one, without overflowing!

Perfect for talent shows, birthday parties, stage shows, classrooms and gospel/ministry magic!

You start with a small glass of milk, and pour it into a larger glass.
Your audience would expect that you would only be able to fill half the larger glass- but NO!
As you pour, you fill the larger glass!
Next, you take that larger lgass, and pour the milk into an even larger glass.
Again the larger glass becomes full!
Of course, you go on to fill the next biggest glass as well!
You end up with a GIANT full glass of milk- all from that first small glass!
Where did the extra milk come from??

You can end the routine there, or you can really blow their minds.
Take the giant glass, and pour the milk into the next SMALLER one.
You'd think that there would be too much milk, and the milk would overflow.
But no!
The milk has shrunk, and now exactly fills the smaller glass.
Pour that glassful into the next smaller size.
Again no spillover, the amount of milk has again shrunk and only fills the smaller glass.
Finally, you end up with the original small glass full of milk.
Where did the all the extra milk go??
What a finale!

The glasses are a matched set of heavyweight clear plastic, with a clever design to make the set more deceptive to use.

This is not a closeup trick.
It is best to perform this trick at a distance from your audience, like from a stage.
The milk will show up well from a distance, and is easy to see.
We recommend using a tray underneath the glasses, as Peter does in the video, because you probably will spill some liquid.

Make sure to wash the glasses as soon as possible after use, or they will stain.
Use mild soap and warm water, and dry with a lint-free towel or cloth.
DO NOT USE abrasive cleanser or a scrub pad or you will scratch the plastic!

Tips & Ideas

Care Tips For the Milk Trick:

  • Keep it clean!
    Make sure to thoroughly rinse and dry the plastic glasses as soon as possible after each use.
    DO NOT use a regular scrubbing pad or any type of abrasive cleanser on the plastic, as it will cause scratches and make the glasses look cloudy.
    The most effective and safe way to clean the outside of the glasses is with a sponge called SCRUB DADDY.
    SCRUB DADDY transforms from a stiff scrubber into a soft sponge simply by soaking it in hot or cold water.
    Most importantly, it cleans plastic without scratching.
    First use it stiff, with a dish detergent like DAWN, and lightly scrub down the outside of each glass.
    Then put the sponge in hot water, get it soft, and gently wipe away all the soap residue from the glasses.
    You may dip the glasses in water to rinse, but use WARM (not hot!) water.
    Next, fill each glass with WARM (not hot!) water and add a few drops of detergent to each glass.
    Shake the glasses to get the soapy water inside. Let this sit for 10 minutes.
    Then rinse all the glasses well.

  • Don't use real milk.
    You probably should not use regular cow's milk with this routine, as milk can spoil quickly if not refrigerated and because of the fat content, can be difficult to rinse out of the glasses. Here are some options:
    • Option 1: Use soy milk, which comes in shelf-stable varieties and can be sipped during the routine to prove that it's real milk.
    • Option 2: Mix up some powdered milk just before showtime. Again, the milk can be sipped, and it is easy to transport because you keep it in powdered form until you use it.
    • Option 3: NOT RECOMMENDED to use the solution marketed as OOM. This is concentrated machinist's cutting oil which, when mixed with water, turns the water a milky color. It's not suitable to be ingested! It also has a strong smell; your audience will know it's not real milk, and will mistakenly think that the trick works by using some sort of fake milk. Plus the oil will cause your pitcher to discolor over time. Not good!
    • Option 4: Use water colored with food coloring. This trick can be performed as "More Lemonade" or "More Juice" instead of "More Milk". Colored liquids show up great from a distance.
  • Use a tray under the glasses
    This trick is a bit messy, but that's what makes it convincing.
    You WILL drip some milk as you pour, and that will prove to your audience that you are really pouring the milk (which you ARE!) rather than using some sealed gimmicked cup or something.
    But you need to protect your performing surface from the spilled milk.
    Use a tray with handles.
    The tray will let you move the set of glasses to your table when you are ready to perform the trick, and will let you easily take all the glasses away when you are done.
    Plus, your table will stay clean and dry!

A Classic Effect, Also Good For Gospel Magic
I used this in a message about how when we help people, the effect is multiplied and it was a great illustration. I can also see it being used to illustrate many other lessons. Yo do have to watch your angles a bit and it is best performed on a platform where you are slightly above the audience. I use water with blue food coloring and it shows up great. I did get busted by one lady who figured out how it worked . She showed me afterwards that her daughter had a set of baby doll bottles and cups that use the same principle!
