30lbs of thermite will attract ALOT of attention, but easily enough to cut a car in half Be careful, there are burn bans out in effect for NYS counties and this will be classified as an intentional burn which has fines/jail time wrapped around it.
Tip #1…Mix oxides in accordance and blend with a little denatured alcohol to form shapes which will dry into semi solids. Can be brushed or shaped as a paste before it dries. Tends to crumble when handled hard. Touch off crude thermite with a road flare, next best thing to actually buying magnesium.
We used to weld big shit together with this stuff with my uncle to form machine skids(for lathes, mills, etc). Still used in heavy steel part manufacturing and repair. Don’t come bitching here if you vaporize your hands or burn your garage down. This shit is HOT and nothing will stop the reaction until it burns out.
