Thanks Tom and Thanks to Iain for the link which I have checked out...
That is a cool idea ....haha cool...geddit..!!!
However it does seem a bit pricey for what it is, I can think of a much cheaper more suitable alternative that is readily available in almost any town that has an aquarium shop......yep them tubes they sell for the water/air filters in the aquariums....some of them are identical to this and even come with the scoop fitted and they are only a couple of quid.
