Query: Blowing Big Bubbles   Although street artists have the know-how to blow bubbles over one meter in
length, the bubble width is typically determined by the size of the hoop, or
wand they use. In this article we explore a regime in which, by blowing gently,
we generate bubbles with radius up to ten times larger than the wand. We
observe the big bubbles at lowest air speeds, analogous to the dripping mode
observed in droplet formation. We also explore the impact of the surfactant
chosen to stabilize the bubbles. We are able to create bubbles of comparable
size using either Fairy liquid, a commercially available detergent often used
by street artists, or sodium dodecyl sulfate (SDS) solutions. The bubbles
obtained from Fairy liquid detach from the wand and are stable for several
seconds, however those from SDS tend to burst just before detachment.
