Ok back during the 80's and 90's there was this table top / desk top tilting wave maker that was basically a long acrylic rectangle that had a clear liquid and a blue liquid in it that when it would tilt from side to side would make the blue liquid act like a sea wave and usually there was a boat/dolphin/surfer riding the wave. I haven't seen these in about 5 years but I need to either find the manufacturer of these or find out what the two liquids are in these boredom breakers so that I can make a critical part of an upcoming project for school. Does anyone here remember these and have any idea where I can find out the information? I've googled tilting wave maker, wave making machine, desktop wave maker, desktop wave machine, executive desktop wave display and come up with nothing so far and looking at websites like sharper image didn't help as they don't sell them anymore.
