5 drops is about 1/2 ml. A teaspoon is 5 ml, so if you use 1/8 tsp, you
should be in range.

Actually, there are 60 drops in a teaspoon, but 50 is probably good
enough for a working number.

I thought 60 was way too many when I looked it up, so I took a teaspoon
and an eyedropper and tested. Results varied from 58-62 so 60 it is.
