Prepare to Resist

We are still in this together, but "this" is going to be real different in the very near future. This demands a different kind of "we."

The French Resistance during Nazi occupation played important roles delivering downed Allied airmen back to safety, supplying military intelligence, and acts of sabotage.

The Underground Railroad is estimated to have brought 100,000 freedom seekers to safety between 1810 and 1850.

It's time.

The specifics in the screenshot are a bit "legendy," but the concept is real. Sugar does impede the setting of concrete.

The last time this was posted, someone with more complex knowledge on the subject showed up with backing science that not only is this not true, but it until the mixture is around 10 percent sugar by weight, it has no noticable effect. So unless you're carrying 400 lbs of sugar with you, the only thing you'd do is risk arrest.

And I quote: Beyond 0.06% use of sugar it is found that the both initial and final setting times drastically reduces.

and a ton is 2000 lbs and we need only 0.1% to 0.2% of the mass to be sugar to significantly reduce setting times and cause concrete to be prone to crumbling Or 2 to 4 lbs for those that can't math.

So not far off in terms of sabotage but not precisely correct in terms of the exact effects produced.

But the lesson can be better generalized, altering things from the engineered specification can with only subtle actions make breaking changes.

Like the loading dock manager in the 1980s in Intel that cost them billions by opening the wafer containers and trying to count them... https://www.youtube.com/watch?v=NGFhc8R_uO4

My understanding is that sugar delays the setting of the cement but doesn't stop it entirely. I've heard of sugar being dumped into loads of cement that workers didn't have time to finish pouring and smoothing out.

Anyways.. here's what happens when you mix stump remover and cotton during a thunderstorm.

Please be sure enough is used. You don't want to end up with marginally compromised concrete that stands up to construction but fails in a couple years killing the inmates.

I heard this firsthand from a materials science professor focusing on concrete mineralogy.
FYI, Sugar cubes can be fired via slingshot.
