A gallon paint can full of thermite can be lit with a sparkler
Harbor freight sells battery powered hammer drills and masonry bits that are cheap and powerful enough to drill a few inches into concrete in under a minute.
They also had saws and saw blades used for cutting up masonry.
With enough thermite anything is possible
I know this is completely off topic, but one of the better Things I Won’t Work With entries about chlorine triflouride:
It is, of course, extremely toxic, but that’s the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water-with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.
You can find all of the blogs here and I highly recommend them.
Thank you for linking that blog. I <3 that whole series, and coincidentally noticed my bookmark no longer worked over the weekend.
I’ve got something long and hard for stars.
It’s a telescope.
A few hits with a pickaxe would be a good test
Its free with your own sledge or jackhammer
strong acids can damage or destroy the Hollywood Walk of Fame stars.
It’s weakest at the edges of the block, not the star.
These comments do not disappoint
I say we take off and nuke the entire site from orbit.
It’s the only way to be sure.
Depends on the amount of destructive power at hand. Plasma torch makes it easy but nuke definitely makes it easier.
Not sure I’d go with a plasma torch, what with the air compressor, and it would be all fiddly to get a good ground, assuming the stars are metal even.
That said, oxy acetylene would work well….
Any ground celebrating fascists is not good ground anyway
I don’t know of any plasma torches that can come along in a backpack but you can get a lot of good work done fast with a battery powered angle grinder. Occasionally I take mine out in my neighborhood when some asshole has padlocked their sandwich-board ad to a lamppost.
