The latest Maplin Catalogue is now offering a gas cylinder and 30 balloons
for £39.

As a matter of interest you might like to know that one cubic meter of
balloon gas will lift one kilo.

Thanks Martin.
 
That's an interesting fact.
I had in mind something 'industrial' in scale - An advertising blimp etc.
Hence the interest in the industrial scale of the gas supply, but good to know from members of the group that balloon gas is widely available.
 
I wonder how the lifting capability of Hydrogen compares to the balloon gas?
It has several major disadvantages - small atomic size so it leaks quickly, not to mention the  real posibility of re-creating the Hindenberg disaster. but it has the best lift capability.
