I've got access to some very large used catering size food oil cans.
They are quite colourful and thought it would be fun to grow some veg in
them. i've seen this done in South america. But I'm at a loss as how to
remove the lids, as at present all they have are holes punched in the
top to get out the oil. I'm sure my normal kitchen can opener would not
cope with the thickness of the metal. Any suggestions?


Offset aviation snips, either right or left cut would make short work
of a can lid.
Here's one example: http://www.tinnerstools.com/wimeofsncu.html
