The Secret To Really Bright Glow Milk Plastic

ByShelley Brewer Posted: Updated:

We love milk plastic, the opportunities for creation are endless! Recently, we made glow milk plastic. It was a fun exercise and the results made everyone extremely happy. But then I came across an idea from one of my fellow STEAM Kids authors that I thought might really kick these up a notch. The results were fantastic!

The results can be used as toys, game pieces, in sensory bins, jewelry and so much more. The only limitation is your imagination!

So when we made our glow milk plastic toys that fluoresced under black light, we thought they were pretty awesome for Halloween.

But then I came across an idea from my fellow STEAM Kids author at Babble Dabble Do. I wasn’t sure it would work, but I thought it was worth a try.

It seemed almost too good to be true. That a simple household item could make such a difference.

So I grabbed a piece, painted it with the new liquid, and turned on my black light.

The results were stunning! Such a difference!

Next I wanted to see if it would last. I painted a handful of our pieces and left the rest so I would have them as a comparison. Then I waited a week to see what would happen.

When I looked at the pieces I couldn’t tell which ones had been painted with the magic liquid. They all looked the same.

But then I turned on the black light. Eureka! It worked! You can really see the difference between the ones in the left that were treated with the secret ingredient and those on the right that were left plain.

I thought once the liquid dried the brightness would fade, but it didn’t they are still super bright! And it didn’t damage the milk plastic structure. They are still nice hard, plastic trinkets. They just glow so much brighter!

So what is the secret ingredient for our super bright glow milk plastic?

Laundry soap!

Crazy.

But just look at the difference!
