I’m trying to invent something, so I went to my local Michaels and picked up “Alumilite™ Amazing Mold Rubber”. I found a few videos on how to make a 2 piece mold, and I think the mold came out pretty good. My problem is my invention needs to be slightly stretchy like a rubber band, not where it doubles in size just about 1/2 inch stretch. Any suggestions on what material to put inside the mold?

You will need to cast it with another silicone. (Be sure to use a good mold release, otherwise, you will cast one big block of silicone!)
