I found a source for free pink foam fuses
OK so the foam isnt really a fuse, you have to do a little work first, but the foam is free.
My local Home Depot does not carry 2" thick pink or blue foam, but they do carry 1/2" and 3/4" sheets. In between every 25 or so sheets there are three pieces of scrap 2" thick by 6" wide by 4 foot long pieces of foam. To me these looked perfect for scratch building a fuse. Im sure they could also be used for other stuff also. Anyway i just grabbed a few of them and told one of the employes that i was going to take them. He said that was fine because as the sheets get sold they just throw the 2" thick stuff away. Well just thoght id let you guys and gals know!
