[quote]QUOTE: Styrofoam is a good choice, but you have to make sure it is yellow or pink, dense styrofoam at least 2 inches thick. Anything thinner will be too flimsy and easily broken. [/quote] Or blue. What you want is extruded styrofoam sold for insulation. The color depends on the manufacturer. You don't need to get 2" thick foam if you are putting it on a solid surface - just allow for how far below grade you need for gulleys, etc. You can use layers to get the desired thickness if you want. <br /> <br /> [quote]QUOTE: Latex caulking and latex based paints can be used without harming syyrofoam, but liquid nails and other adhesives containing petroleum distillates will dissolve it. [/quote] Good point - use water based paints, etc. Note there is a Liquid Nails for Projects" that is compatiable with foam. <br /> <br />[quote]QUOTE: If you want to dig a pond or lake, spray some type of product containing petroleum distillates and let it dissolve the styrofoam to the desired depth, then spray with water to stop the action of the distillate. [/quote]I've never tried this, but it doesn't sound like it would allow much control over what you're doing, and also sounds like it could produce some pretty heinous fumes and smells. I converted my soldering gun into a hot-wire cutter by replacing the soldering tip with a piece of bare copper wire, 16 AWG or so, bent into the shape of the 'gouge' I wanted to cut.
