The Universal Law of Convex Meniscus

As I picked up the container of the Starbucks cold Black coffee ready to pour it, like I do everyday to start my morning, my mind went into immediate calculation mode.

“It could be.”

“It definitely could be.”

My mind was referring to the quest for the all elusive exact match of the amount of liquid left in the container with the maximum capacity of liquid to be held in my glass search I’ve always been on.

The quest for such things makes life interesting. Cosmic.

The other day, while pumping gas, the pump stopped on exactly $40.00

I know there is a 1 in 100 chance of it happening, for the pump to stop at 0.00, but it seems like I’ve pumped my gas thousands of times and I don’t recall it happening more than once or twice.

A mathematical anomaly.

Getting back to the capacity of my glass and the amount of dark coffee left in my container, as I started to pour the coffee into the glass my suspicion grew.

At the halfway point I truly felt that this could be the match.

Three quarters worth of pouring and my excitement built.

Then it happened.

The glass was full and the container was emptied.

An exact match.

I stood before my glass with awe.

As I went to throw out the empty container of coffee my heart dropped.

There was more left in the container. Not much more, but more.

I had to push the envelope.

Standing over my full glass of cold black coffee I raised the near empty container above the glass and slowly turned it upside down.

Slowly, very slowly, I transferred the remaining liquid contents from the container into the glass.

The glass wasn’t full after all.

It absorbed more.

The liquid rose to the top rim of the glass.

I had to keep going.

I picked up the container of black coffee and looked inside it. There had to be another drop left inside there.

There was.

So I chanced a near perfect match with my curiosity to see how much my glass could hold.

Without spillage.

I really thought I was going to cause spillage and ruin a perfect match of capacity of glass to volume of liquid left in container.

So, I very carefully tilted the container.

After some time, a drip of darkness appeared and fell into the full glass.

No spillage.


Why was the perceived 100% full glass able to absorb more?

A convex meniscus occurred.

The amount of liquid raised above the rim of the glass in a curve to prevent spillage.

Our lives are the same way.

This is a very important piece of how the universe operates to understand.

As soon as we think our lives are full of darkness, when we feel we absolutely can not take one more thing happening, without losing it, without spilling over, we are introduced to the Universal law of Convex Meniscus and we learn that we can.

Only when it is absolutely needed, The Universal law of Convex meniscus appears in our lives.

It may appear through a loved one taking on some of the volume in our lives, or a friend receding the waters by providing an ear to listen to our worries, or by us believing we can take on more in our lives, more above the rim, the point where it doesn’t make logical sense to be able to store more.

When you feel your life is full, remember this picture of my cold Starbucks black coffee.

You can take on more than you think.

Convex meniscus.

What a concept.

Family, friends, loved ones, kindness live above the rim of our lives.

They are the reason we are able to handle more than our glass worth.
