Hi,
I'm not sure whether this would work or not but one possibility is using an
inner tube from a mountain bike tyre. They are strong, reasonably light and
look to be just the right size. Also small holes could be made on the inside of
the skirt to blow air in to the underside (as mentioned by someone else). As
for the motor/fan issue then I'm not sure but I guess model aeroplane shops
would be the best bet. Ducted fan models of fast jets are quite popular but I
think the torque required to drive one would be quite high.
Cheers,
Lee
PS The inner tube would have to be cut to make it a smaller diameter but it
should be reasonably easy to glue the two ends together.
