8 gargantuan relics

1: Pizzle dozers from mars: It turns to ice on mars and they need huge electric scrappers. But then they left and the dozers have startedto rust away to hulks.
2: An electric razor the size of Manhatten: Artists are strange chaps! Who knows what the fella's will build next? I guess if you were a giant you could make some use of it.
3: It's made of stone and covered in vines but it's outside of some shops in the highstreet. It's a statue!
4: Fat old politician.
5: They drove a bus into a hole and painted it black many years ago. It is the monolith.
6: Birds of prey have been pecking at it for years but the giant Pigeonistan will never fall.
7: My ass.
8: Men called Micheal built it to reflect some glory. It is "the Flask".
