The ad for this bionicle 'tub' came out last Sunday. I stopped in today (Thursday) and they had five on the shelf (Las Vegas). I picked some up for a friend. I'm not into bionicle, but this does look fun to play with. :) Corey www.brickitgood.com (20 years ago, 9-Apr-04, to lugnet.technic.bionicle, lugnet.general, lugnet.market.shopping, FTX)

(...) The amount that a fluid can be compressed varies with the fluid, the temperature, the pressure and other things. Water can be compressed too much - that's why trucks don't use it for their hydraulic systems. Hydraulic fluid is special oil that (...) (20 years ago, 8-Apr-04, to lugnet.technic)
