OK, you try it and we'll watch.


well anyone who has a gas stove knows the danger that it will strike
back through the gas mains into he gasometer down the road and blow the
town up every time you want to boil a kettle.

Even my old gran knew that in 1955.

Thats why she had a coal range.

Er but the catalyst didn't come alonguntil the 60,s

It took Servotomic to make boiling a kettle slightly more dangerous
than being on a terrorist hit list.

As the saying went at the time "the IRA give warnings, Servotomic
don't"
