How to make gelatin bubbles, explained well and entertainingly :-D (and, yes, make them of flavored gelatin the same way, and they'll taste like the flavored gelatin... the flavors won't change the qualities of the gelatin much.)
How to Make Gelatin Bubbles #2: Gelatin mixture: 2 parts cold water to 1 part unflavored gelatin (like Knox). Start by putting your cold water into a microwave safe bowl. Add a little luster dust, amount will depend on how translucent you want your bubble, I normally did about 1/8 tsp or less. Food color can also be used, but remember gelatin is a little yellow so will change your color slightly. I used super pearl but have used many others.
