Just a little note:

 I've had quite a few requests to build custom Ferrocells using "mouse milk'
 and other diluted versions of my mixture. Please refrain from asking me to
 make these custom formulae as my tests and experiments with these mixtures
 have proven them to be of lesser quality than my current Ferrofluid mix,
 methods and procedures.     
I'll continue to refine these products to give the
best possible experience you can have.
