The model railway houses were sent to me by a fan - and I wasn't really excited about crushing them - I thought these little houses would break way too easily - but then it was really fun to crush them. They wouldn't break when I was just standing on them - so I used them as "step stones" at first. But of course I wanted to trash them - so I got up on each one with both feet and started bouncing until they broke apart ;-) In the end there's not much left but a bunch of plastic splinters :-)
