Xanthan gum is WAY cheaper!!! You can mix it with things like cake batter and or shaving cream and oil to make different thicknesses and consistencies... I highly recommend xanthan gum for any gunger... it goes a long way too! I get mine on Amazon... just shop around there because you'll find prices will fluctuate.
Get yourself some 5-gallon buckets, a power drill, and a large mixing attachment. It will save your life!
Xanthan gum is also a great fisting lube if you're into that sort of thing... not better than x-lube but it will work if you are a fister and like gunge.
So, the recipe I tried (I did this x5, as I had 5 boxes of cake mix): 1 box of cake mix 1 cup of water ~2 seconds of spraying out shaving gel A "light dusting" of Xanthan gum ~3 drops of food coloring
I included a picture of what this recipe kindof looked like.
I used a drill with a mixer attachment to blend everything. I would recommend mixing after each box of cake mix + friends has been added.
