Water is dynamic.
Hydrogen-bond networks form and reorganize rapidly in liquid water. These findings concern water itself and do not demonstrate an effect from sealed crystals.
SLACKSTONE II PLUS
The everyday wonder of water.
Some of the best rituals begin with a glass of water. Meet the sealed glass ampoule that brings a little curiosity and intention to an everyday moment.
Thoughtful by design. Rooted in Spain, 1966.
THE ART OF PAYING ATTENTION.A FEW SIMPLE TRUTHS
01
Always sealed
The glass stays closed throughout use.
02
Nothing to mix
No powders, drops, or measuring.
03
A daily companion
A simple practice with clear instructions.
A DIFFERENT WAY TO THINK ABOUT WATER
What if the most familiar part of your day felt new again?
We think about the food we eat, the air we breathe, and the way we rest. Water deserves a moment of attention, too.
SLACKSTONE II Plus is a sealed glass object designed for a simple, repeatable water ritual. Its roots go back to Spain in 1966. Its place is in everyday life.
THE OBJECT
A quiet moment, made tangible.
Inspired by a design with roots in Spain in 1966. A sealed glass ampoule for an intentional water routine.
A SCIENCE-LED CURIOSITY
Water is remarkable. Let's stay curious.
Water has a rich physical story, from its constantly moving molecules to the hydrogen bonds that briefly connect them. Understanding that science is a starting point for good questions, not proof that a particular product changes water.
Conceptual visualization of water, not a demonstration of a SLACKSTONE effect.
ESTABLISHED WATER SCIENCE
A constantly moving molecular world.
In liquid water, neighboring molecules interact through hydrogen bonds. These connections continually rearrange. Researchers investigate them using ultrafast spectroscopic techniques.
Research timescalesfs → ps
Femtoseconds to picoseconds describe experiments on liquid water, not product performance.
Could a sealed object make a measurable difference?
SLACKSTONE II Plus brings a sealed mineral-crystal ampoule into a water ritual. Whether water differs measurably after contact with the outside of that sealed glass is a product-specific hypothesis requiring controlled tests.
What has been demonstrated?
We do not currently present independent product-specific studies establishing changes to water properties or human hydration outcomes from using SLACKSTONE II Plus.
THE SCIENTIFIC METHOD
From an interesting idea to reliable evidence.
A meaningful result needs more than a compelling explanation. It needs a fair test, measurements and independent replication.
01Compare fairly
Use identical water and glass containers, with sealed-ampoule and sham controls, under blinded conditions.
02Measure carefully
Check predefined outcomes such as pH, conductivity, dissolved gases or appropriate spectroscopy, with calibrated methods.
03Repeat independently
Publish methods and uncertainty; reproduce any effects in independent laboratories before drawing conclusions.
EXPLORE THE RESEARCH
Read the underlying water science.
These peer-reviewed studies examine liquid water. They are educational references, not trials of SLACKSTONE II Plus.
THE SLACKSTONE II APPROACH
The smallest daily moments are worth noticing.
There is something beautiful about a ritual you can return to. SLACKSTONE II Plus gives an ordinary glass of water a place in your day.
The mineral crystals remain enclosed in sealed glass. Keep the ampoule closed and follow the instructions included in your box.
Nothing to mix. Nothing to measure.
How to useA LITTLE CLARITY
Curiosity is good. Clarity is better.
Here is what you should know before bringing SLACKSTONE II Plus into your day.

A LITTLE CLARITY
Good questions. Clear answers.
Everything you need to feel comfortable getting started.
ContactDo I open the ampoule?
No. Keep it sealed throughout use. Inspect the glass before each use and do not use a cracked or damaged ampoule.
What comes in the box?
SLACKSTONE II Plus includes two sealed glass ampoules and product instructions.
How do I begin?
Place the ampoule in a glass of water, narrow end up. The current product directions specify a 24-hour wait before first use. Read and follow the enclosed instructions.
Is this a water filter?
No. Use safe drinking water. SLACKSTONE II Plus does not replace filtration, disinfection, or water purification.
Can I choose a delivery plan?
Available subscription plans appear on the product page with their current price and delivery terms. A subscription is a recurring purchase. Review the plan terms before checking out.
