I took a soup can and an old palm sander to make a mixer for the colorants, WORKS GREAT!!! the only issue I see with this is, a can opener that cuts the outside of the seal would be better, or as I will do, is apply a small piece of pvc hose cut length wise to cover the sharp edge.
1.50 chicken Noodle soup
1.00 couple of cable ties
Old garage sale find palm sander
If you look closely you can see where the sharp edge started rubbing on the colorant bottle. The colorant does have 2 stainless nuts in the container also
