Good old Tesco’s: Britain’s biggest and richest supermarket. Not only are they able to still eek out impressive profits in these dark financial days, but they also seem to be able to change the effect of microwaves upon metal. How else can we explain this wonderful cast iron Le Creuset casserole which also appears to be MICROWAVE SAFE. That’s Cast Iron + Microwaves.

Can any budding physicists tell me what they think would happen and if anyone has a microwave and a similar Le Creuset cast iron casserole dish they want to test it on please do. Else follow my three step plan to instant profit:

1) Buy casserole from Tesco
2) Microwave (stand back)
3) Sue Tesco for false advertising
