TRIVIA TODAY - MOnday, May 2, 2011
Greetings Infomaniacs,
Yesterday we celebrated my godson's 6th birthday, and all
he wanted for his big day was some colored bubbles. I
searched online for a brand that wouldn't stain, and came
up with something called Zubble Magic bubbles.
He LOVED them, and spent a good part of the afternoon blowing
pink and blue bubbles in the backyard.
I had a moment of panic when he spilled some of his bubble
juice, and there was a pink blob on the deck, but a few
minutes later, it disappeared! Whew! Since my mind was on
bubbles, I thought I'd share some interesting bubble facts
with you...
Enjoy!

RANDOM TIDBITS
A bubble, like a balloon, is a very thin skin surrounding
a volume of air. The rubber skin of the balloon is elastic
and stretches when inflated.
***
If you blow a bubble and close the opening by flipping the
wand over, the tension in the bubble skin tries to shrink
the bubble into a shape with the smallest possible surface
area for the volume of air it contains.
***
Since bubbles always try to minimize surface area, two
bubbles will merge to share a common wall. If the bubbles
are the same size as the bubbles to the left, this wall
will be flat. If the bubbles are different sized, the
smaller bubble, which always has a higher internal
pressure, will bulge into the larger bubble.

Bubble Art
Who knew bubbles could be so gorgeous and that they could
defy gravity and logic as we know it. It's amazing the
things soap bubble artist Fan Yang can do. His show is a
sell out in New York and he has appeared on David Letterman.

***********************************************************
If you ever try to blow bubbles with just pure water, it
won't work. The surface tension in plain water is just too
strong for bubbles to last for any length of time. One other
problem with pure water bubbles is evaporation: the surface
quickly becomes thin, causing them to pop.
***
When two waves of light combine, the waves can meet each
other crest-to-crest, adding up and reinforcing the effect
of each other, or they can meet crest-to-trough, cancelling
each other out so that they have no effect. When they meet
crest-to-trough, for every "up" vibration in one wave,
there is a corresponding "down" vibration in the other wave.
This combination of equal ups and downs causes complete
cancellation or interference. Interference is responsible
for the color of bubbles.
***
If you let a bubble hang from a bubble wand for awhile,
the interference colors begin forming horizontal stripes -
because the bubble film is thicker at the bottom than at
the top, forming a wedge shape. As the bubble drains, the
wedge of bubble solution gets thinner and thinner.

hay 25 ft. away from him. Yet the horse is able to eat from
the bail of hay. How is this possible?
