0iminthebathroom 10 years ago um, its on instructables, but for a quick response. 100% clear silicone caulk mixed with corn starch in ratios ranging from 1:1 to 5:1 to 1:5 to produce a quick setting, semi firm silicone item. It can be hand molded after several minutes of setting up, or poured like cake icing when freshly mixed . More cornstarch equals quicker set and cure time. DIY version of sugru, I have used it in my ghost making instructable for casting the face and other tasks around the house.
