Well good luck. Its not easy getting good recipes for quality slime. I have tried a few home made do it yourself recipes that left me sometimes frustrated. Alot of searches on line led me to ingredients but the right mixture is the key. So far methyl cellulose, j-lube have been the most successful combo. Gaur gum and borax have been the most frustrating in getting that right mixture. For quicsand home brew my best mix has been sodium polyacylate and fine sifted peat-moss, that got me off without manual stimulation, and the wife too.
Cake batter, water, and applesauce...... That has always worked well for me. Just the other night I used instant mash potatoes..... wasn't "slime" but it had a great gloopy consistency, but didn't stick. Thinking of combining the cake batter with the mash potatoes next.
