Operation Plumbbob

Propulsion of steel plate cap

During the Pascal-B nuclear test, a 900-kilogram (2,000 lb) steel plate cap (a piece of armor plate) was blasted off the top of a test shaft at a speed of more than 66 km/s (41 mi/s; 240,000 km/h; 150,000 mph). Before the test, experimental designer Dr. Brownlee had estimated that the nuclear explosion, combined with the specific design of the shaft, would accelerate the plate to approximately six times Earth's escape velocity.[9] The plate was never found, but Dr. Brownlee believes that the plate did not leave the atmosphere, as it may even have been vaporized by compression heating of the atmosphere due to its high speed. The calculated velocity was sufficiently interesting that the crew trained a high-speed camera on the plate, which unfortunately only appeared in one frame, but this nevertheless gave a very high lower bound for its speed. After the event, Dr. Robert R. Brownlee described the best estimate of the cover's speed from the photographic evidence as "going like a bat out of hell!"[9][10]

Just "straight up" doesn't get you into earth orbit without a circularization burn. Enough up and you get to skip earth orbit and go straight to a solar orbit, but that's probably also enough energy to turn iron into iron vapor, so.

How do they test that something is dangerous to the eyes? Did some poor chimp get acid dripped into its eyeballs?

Easy, everything that isn't meant to go in your eyes is dangerous to eyes. The more reactive it is, the worse it's going to be. No one needs to squirt a rat in a face with a fracking fluid that melts plastics to figure that out that it's not going to be a Visine replacement.

Animals testing gets done if something needs to be tested to be safe for eyes, severity of damage/irritation, or to learn about treatments.

They use rabbits primarily for eye safety tests, anyway. And yes, some of the them did in the past get blinded with nasty chemicals just to prove they actually did. Millions of animals have been sacrificed for medical and human safety experiments through the years, providing unique and valuable data we could not have obtained any other way.

"Just how dangerous is it?" is a question that needs to be answered, and we use laboratory animals to get those answers. Thousands of them for most tests so as to get statistically meaningful results. No point in making it sound better than it is. It's a grisly business, but necessary to advance human health.

You're right about fracking fluid, though, and other formulated products like that. They generally won't test the finished product if they have a good idea of what the components are and what each will do individually. They can model pretty accurately the combined effect. They do try to minimize the number of animals needed.

In some alternate universe, the manhole cover leaves atmosphere, then turns back, in the meanwhile earth has rotated enough that the cover splashes on Kremlin killing Khruschev and igniting WW3.

Every time we get flooded there's plenty of news coverage of school run mothers and travelling salespeople who think that they know how to ford or drive through water, not realising that their SUV isn't a magical boat car or that their poverty spec BMW has an airbox less than a foot off the ground.

Well best case it's traveled ~124 billion miles since October 7th 1957 (last date of those tests) but the solar system has a radius of 144 billion miles (orbit of Neptune) so somewhere near the orbit of Neptune.

did some quickie calcs, and the drag force (at 10,000 ft altitude) experienced by a spherical object approximating the size of that cap would approach 4 billion newtons. i could see one ton of steel resisting the heat long enough to clear the atmosphere, but not the mechanical stress. change that sphere into a tumbling manhole cover and all bets are off.
