Morning Stretchy!

Same, Durd. Same.

But get yourself back together.

It’s only Monday, dammit.

While Durd figures himself out, let’s talk about Silly Putty.

Because the stuff was invented to defeat the Japanese in WWII.


Imaginative, but not quite.

It was 1943.

This GE engineer, James Wright, gets a new project on his desk.

So James gets to work.

But he kinda wasn’t paying attention…


This is an ad. And you’re under arrest.

Cause of arrest?

Your sh*tty videos.

Work with our video editors instead.

Just send over an idea with files and get back eye-searing, brain-melting, explainer videos, ads, product demos, and clips.

Join the waitlist, comrade. We want you

So anyway, when James gets to mixing up new rubber formulas, he runs into a problem:

James got no idea if the other rubber ingredient is borates or borax or bismuth or…

Yaaaa wrong choice, James.

That’s James’ silicone oil and boric acid rubber.

But, rubber’s supposed to be – ya know, rubber.

And James’ creation?

James’ creation could kind of flow:

And bounce:

And stretch:

And…randomly transfer newspaper ink onto itself??

All together, this accidental rubber thing was kinda cool!

So James names his new invention nutty putty and starts selling it for $1.

Then after the war ends, James rebrands his nutty putty as silly putty:

And his ‘real solid liquid’ sold 300,000,000 units.

Stay Cute,
