Hey, that's nothin'. I made a working Sherman tank when I was 12 that I could get in and fire out of. Of course right below the US Army Hell on Wheels symbol it said Maytag heavy load washing machine---and unfortunately right after a heavy rain it got soggy and collapsed into the flattened cardboard box that my mom's new washer came in.
But until it did, it destroyed 5 Panthers, 3 Tigers, a Panzer IV, and 2 Stug IIIB's---Matag makes damn good cardboard tanks. We could have won if not for the damn rain storm. Maytag made a fine Sherman, but it just wouldn't stand up to moisture.
