The physics behind building an enduring soap bubble

Last year I was obsessed with making large bubbles that lasted a while. This was the best recipe:

1 tsp Guar gum 2 tsp baking powder 2Tbs rubbing alcohol 9.5 Tbs Dawn dish soap 15 cups water

Awesome! I've always loved bubbles. I really need to do more with them.

Out of curiosity, did you develop this formula or find it somewhere? Also, what surprised you the most while working on this?

Tell me more!

Has anyone tried making bubbles out of the lipids that cells use for their membrane? And in fact can you actually buy those lipids?

Interesting read! :)
