Make glow-in-the-dark sugru

 First of all, credit to super sugru guru Mallin for encouraging me to push forward with this project! This process makes your favorite fixing substance, sugru, glow-in-the-dark. Shall we call it Glowgru? A friendly caution - please be careful when using the glow powder to avoid getting it in your eyes or mouth! You may choose to use gloves if you wish.

Kit list

  • sugru mixed to the color you want
  • a small cup of warm, soapy water
  • a letter opener or safe sugru-cutting tool
  • glow-in-the-dark powder (can be ordered online)

Step 1

1

Start with a primary color, or mix sugru colors to your liking. To get permission for this product from my wife (who maintains creative approval rights for my fixes) I promised to make it pink. I used sugru's color chart as a start point, and mixed 70% white with 30% red as you see here.

Step 2

Using this method, you can choose to do the entire fix with glowing sugru if you want. I chose to use sugru without mixing it as a base for contrast. Following Mallin's suggestion for another project, I set aside a small portion of sugru for this project.  Also, say hello to Hackbot (the contraption holding the key), my Hands #3 & #4 in my sugru endeavors!

Step 3

For best results, make sure you begin working with the powder very quickly after a) opening your pouch of sugru and b) rolling it to make it tacky! Start by pouring on a small amount of glow powder, roughly covering the portion of sugru you wish to use. The amount you see here is about 1/8th of a teaspoon of powder. The silver underneath the sugru in this photo is one side of the original pouch, cut at the dotted line on the exterior, for scale. Keep the amount of powder small to start. Roll up the sample like a crepe, and over a paper towel or wax paper (some powder will fall out) work the powder into the sugru between your palms.

Step 4

You can repeat the following step about three (3) times before the sugru becomes saturated with powder to the point where it becomes too difficult to easily mold (the sugru becomes mealy and begins to fall apart). Mold the sugru into a little bowl, and add a small amount of powder (the amount above is about 1/10th of a teaspoon). Carefully pinch the rim of the bowl closed with both thumbs and index fingers. Weld it shut and gently roll it into a ball. Be patient, and roll very gently, alternating between rolling it into a short tube shape and back into a ball.

 Apply your new Glowgru to your project and charge it under a light. For instant gratification, use a true UV light...

 ...and marvel at the results! The photo above was helped with a toy/replica Sonic Screwdriver of the 10th Doctor, which comes equipped with a UV light! 

A similar method has already been used for making camping equipment better and I can only hope that this guide will help others solve for and create things like:

-Avoiding stubbed toes in the dark

-Hiding secret "I love you" messages to kids and spouses that can only be seen after lights-out or with a UV blacklight

-Creating holders in the car for phones and MP3 players that don't distract you while driving

-Any situation where you need to find something without turning on the light!

I hope you have fun with this!

Best,

Saul Good

cool idea!

The camping stakes were done by someone else...I don't know who! As far as making it glow brighter, you're absolutely right - just about any way you can slowly add more and more powder, the more (and better) it glows. Keeping an eye on the worktime is very important too, but I've gotten sugru to accept much more by adding small amounts/working it in/repeat. Now, I can get it to glow uniformly, and much brighter.

I need to get some of that powder.

I'm wondering if in addition to working the powder into the sugru, if you could, after you have finished the project but before the sugru sets, pour a little more powder on and work it into the surface for even more glow strength.

Oh, re-reading your camping stakes project it sounds like that is what you might have done with those?

E,

I have been experimenting with adding more glow powder to a pretty good degree of success. It just takes a LOT of patience working with it. Even when you're able to mix a high content of powder, it does tend to make sugru harder during the worktime. However, check out this guide:

I would certainly purchase some Glowgru if it were available. Considering that sugru is just one extant variant of the Formerol platform technology, I would say it's just a matter of time.

Neat idea, but I wish it glowed more. Maybe you will inspire the folks at Sugru to make a glow in the dark version themselves.
