Hi Encaseme,
Many thanks for the two video links. I had not seen the first one before. It is very good.
The second one has to come with a safety message: DON'T TRY THIS YOURSELF !!
There are loads of different types of garbage truck, which compact in different ways. Plus the nice soft bags the stuntman climbed on was not full of broken glass, used hypodermic needles, dog poo, and other nasty stuff.
Remember everybody: Gromet's warnings on Trashcan Stories are there for a purpose.
Cheers,
Daffy
