Comments on How to Make Bubbles

Try 16 parts water to one part dish soap (a cup to a tablespoon or a gallon to a cup).

If you use a whisk to mix it you'll get a lot of foam and you'll need to scrape that off or let it settle (maybe more than a day) or they'll interfere with the effort to get good bubbles.

Dawn or Joy are the best soaps for the bubbles ... but go ahead and experiment, as the author suggests.

Indoors is fine for bubbles and often better than outdoors ...

adding food color doesn't add color to the bubbles. Bubbles have colors because they are nearly as thin or thinner than wavelengths of light. That's the same reason that gasoline on water shows colors. Adding food color doesn't add enough pigment to the film (it's very very thin) it only adds color to the thick drop at the bottom of the bubble.
