I was quite surprised, er during the summer I went to my grandson's school fete  and  they had a hot air balloon  demonstration there and this er, this car turned up with a trailer on the back with, I dunno, probably some name, hot air balloon name on the trailer, I thought oh yes he's  gonna show us how to inflate it and  i I was quite amazed from the time he unpacked the balloon  to the time it actually took off was only ten minutes.
