anyone have any suggestions as to make some water effects without having to buy the very expensive stuff from Woodlands.

How much Bachmann ez HO track do I need for a figure 8 using the 45 degree and the 90 degree crossovers ?    Can I make the figure 8 smaller or larger by not using as many track ? I know that I need 22 curved track to use the 30 degree layout but I don't have that much room.
