Esington Glass 2.0: Solid Iron Nanospheres Large


Raised $196,560 on   Kickstarter

Stylish hourglass filled with iron nanospheres

*The Large glass is our executive edition: 40% taller and 3x bigger. The Large glass has louder white noise. Both are 25-minute timers. Borosilicate glass with 4 million iron nanospheres.

At the End of 2014, we introduced the Esington Glass to the world on Kickstarter. With incredible support from the community, the project raised $196,560 with 2272 backers!

After years of testing and feedback from the community, we're back to solving the biggest problem in timeboxing today: interruptions.

When you get interrupted mid-sprint, you can now stop time.

"Got my Esington today and I am ecstatic! I can't believe how great you handled everything. I am really impressed and grateful for putting this great idea out to the public... I just can't wait to change my life and discipline myself a step at a time to accomplish what I've always wanted to do."- Vanessa C, backer of the original Esington glass.

Esington 2.0

Did you know the average worker gets interrupted after only 11 minutes of work? The crazy thing is it takes 25 minutes to get re-focused on the job.

With Esington 2.0, the magnetic time-stopper will keep your place in the sprint and act like a bookmark for your brain, waiting to be unleashed to restart your work.

Control Time

We invented a new way to control the time on your glass. Simply place the magnetic stopper over the neck of the glass and the timer stops!

The world's first solid iron nanosphere timer with a magnetic time stopper!

It has a cool new magic trick - stop the flow of iron nanospheres with the silicone magnet. The magnetic stopper interrupts the flow of the solid iron nanospheres and keeps your place during your timeboxing sprint.

Hand Blown Artisan Glass

For Esington 2.0, we are using borosilicate glass (like pyrex). Borosilicate glass is a type of glass that contains boron trioxide which allows for a very low coefficient of thermal expansion. This means it will not crack under extreme temperature changes like regular glass. It's a standard 25-minute timer designed for the Esington timeboxing method (similar to the Pomodoro method with a few cue differences). Each Esington Glass is hand blown from a single piece of glass making each vessel unique.

Millions of Iron Nanospheres

Each glass is filled with 4 million solid iron nanospheres - more than 1kg in each glass. These make the glasses unique and give them a wonderful visual effect as the spheres bounce chaotically around the glass. This also produces a wonderful white noise.

The most beautiful productivity timer ever made. The solid Iron nanospheres flow freely, even after thousands of magnetic stops.

Soothing White Noise

Millions of iron nanospheres produce a soothing white noise for the first 15 seconds after turning over the glass. This activates your aural cue to start your sprint.

Magnetic Silicone Stopper

The silicone stopper is designed to have a unique feeling and a satisfying soft "click" into place to stop the timer. This will make it easy to engrain the "bookmark for your brain", and bring you back exactly to where you left off your work when you're ready to resume.

An elegant addition to any executive desk. While the stopper is in place, your brain senses incompletion and will subtly pull you back to your work. You will get a satisfying reward when you pull out the stopper and unlock the timer.

How it works: The Esington Method

The Esington Method uses the Esington Glass as the timer and boils down to 3 simple steps:

  • Turn off all distractions
  • Turn over the glass to activate the 3 cues
  • Work on a single task until your time runs out

he Esignton glass is designed to help you develop a timeboxing habit as quickly and easily as possible. It does this by giving you three powerful cues to train your initial habit:

This unique combination of cues was designed to lower the activation energy required to form the habit. High activation energy is the prime reason habits don’t stick (and why only 8% of people are successful in achieving their New Year's resolutions).


The Esington Method trains your brain to go into the “hyperfocus” mode (also known as "flow") when the above cues are given. This gives you the ability to destroy procrastination with the simple action of turning over the glass. It's the famous "Click-Whirr" phenomenon Robert Cialdini popularized in the book Influence.


  1. You are setting up an ultra-fast work/reward cycle. Once the 25 minutes are up, you are filled with a sense of accomplishment and rewarded with a break. A dopamine rush will ultimately cement the habit in place and change you fundamentally as a person.

  2. Studies show periodic resting increases the quality, quantity, and creativity of your work.

  3. You destroy what’s known as Parkinson’s law, which states that people and organizations will fill up and use all of the available time given to a particular task. For example, if you’re told you have a week to write a report, it will likely take you an entire week to get it done. Once you implement timeboxing, since you are given so little time to “sprint”, you may finish that report in one or two sprints.


The Esington timer has a “soft stop”. There are no annoying bells or beeps to signal the end of your cycle.

The timer runs out gracefully. Sometimes, your focus can take you well beyond 25 minutes, and that’s ok (especially if working on lower-energy tasks like answering emails). You don’t want to lose a valuable train of thought. Just be sure to rest proportionally to the energy spent working.
