Ok first hello every one. I havn't been on these board in a long time since my out of state move. I was hoping you would still help me. I need to make a science project of an animal cell, I was thinking I could use the same stuff that would create a pond or lake. What is is called (I forgot) but I want to lay one layer of it, then put all the cell stuff in it, then lay more of the clear lake stuff on top then, voila! Instant cell. Please don't chastise me for putting this on a railroading board but, I have made some pretty kicken stuff with my limited knowledge of model railroading landscape skills. Thanks to you all.
