  They act a bit like a balloon really – you fill them up with gas, but when you stop blowing, the gas will come rushing out again. You just have to control the width of the pipe from the tank so that the air comes out slowly.
  Some hydrogen car records for you – the fastest speed one has ever done is 207 mph and Toyota are releasing a car that will be able to travel for 300 miles on one tank of fuel (thats about 3/4 the distance my ford fiesta can manage). By putting MOFs in the tanks of these cars you can store about three times as much gas – so that means they would be able to travel three times further!
