Diminishing Milk Glasses


Show a set of 4 clear tumblers. Each cup is a similar shape and design and each is twice as large as the one next to it. Pour milk from the largest tumbler into the second largest. Even though it’s bigger, the milk perfectly fills the second cup with none left over. Then pour the milk into the third cup, and finally into the smallest. The milk fills the cup each time with no extra.

Or do it in reverse, filling the glasses from the smallest to largest. Or, if you want, at the end, use the smallest cup to fill the biggest. Special trick glasses and instructions included. 

Plus, as an extra benefit, you don’t really have to use real milk. Add some Miracle Milk to water. It looks like real milk and helps you avoid any tricky clean-up or after-milk smells. Miracle Milk will help keep your equipment clean.

This trick is great for making any three or four points. As you talk, pour the milk from one cup to another. For example:

  • God loves you (John 3:16).
  • We all have a sin problem (Romans 3:23).
  • God sent Jesus to be the Savior of the World (1 John 4:14).
  • You can have eternal life if you are willing to receive Him (John 1:12).

Then at the end, pour the small cup back into the large cup to completely fill it and emphasize that what you’ve been teaching them is the truth and you want them to know the truth so that they won’t get tricked by the lies and ways of the world. Things are not always the way they seem. 

There are multiple other ways to use this trick as well. For example:

  • Passing along the Good News.
  • Sharing with others.
  • How when you give to God, He gives back to you.
  • How God will always provide. 
  • Bible stories like Jesus feeding the 5,000, the widow’s oil that didn’t run out, and any other miracle that people might think is “impossible.”
