does anyone know roughly how many pounds one of the old vw bug shells weigh? i have a fantastic prank in mind for my highschool that consists of using 2 of them welded together, and i need to know how much they weigh so i can know how many ppl to recruit for it.

also, is there such a thing as a portable welder? because it would be easier to just weld them in the courtyard instead of carring 2 welded already...and if there is, how much would it cost to rent?
