What Is Tritium?

Let’s get technical for a little bit.  What is this tritium stuff? Well I’m glad you asked!  Per www.physics.isu.edu “Tritium is a radioactive form of hydrogen, used in research, fusion reactors and neutron generators… By mixing tritium with a chemical that emits light in the presence of radiation, a phosphor, a continuous light source is made.”

So apart from being used in science-y stuff, tritium, in a glass tube, combined with a phosphor makes for awesome little glow-vials to put in all your favourite gadgets. You may have already seen this in watches, exit signs, knives and now spinners.

“Can I put awesome little glowy things in my spinner?” I hear you ask.

Well, the answer is, probably!

How Do I Install Tritium in My Fidget Spinner?

Let’s start by having a look at your spinner.  First, does it have pre-made slots that can house a standard sized tritium vial?  If yes, then you’re well on your way to a finger-disco.

Some manufacturers are designing their spinner with this specific mod in mind.

Stealth Tritium Design

I may have even seen a sneak-peek of a new design by Stealth Spinners, which is designed for seriously spectacular tritium vial placement.

I might just pause here to say that getting your hands-on tritium vials is very dependent on where you’re from. Just do a google search for a local supplier and speak to a local expert about the conditions of sale relevant to you.

How Do I Attach Tritium To My Fidget Spinner?

Now, you’ll need some kind of adhesive.  The consensus seems to be that Norland 61 is the best for this particular purpose. It is crystal clear and has a relatively easy cure time and application method.

Some tips and tricks I’ve come across include filling the slot to halfway with the glue and then pushing the vial into the glue so that you get an even coverage with minimal bubbles.  Using a syringe seems to be the preferred method of getting the glue where it needs to be.

The Stealth Aventador and B2 Spinners are both tritium compatible for 6 mm x 1.5 mm vials.

Once you’re happy with the placement of your mini glow-rods you need to expose the Norland 61 to UV light to cure.  The number one tip I found here is to visit your friendly nail artist and beg to use one of their UV curing nail-beds if there’s one spare. I know right? Genius!

Still Have Questions?

If you’re still unsure about this one don’t forget to stop-by at the repository of all knowledge relating to spinners – Spin Space – the Facebook group.  You’ll be sure to be pointed to loads of great info, and may even meet some people that have done this and can walk you through it!
