A random drawing assigned me number 13, like a character from the TV
program The Prisoner. Number 9, Don Rathjen, was now
onstage. We were two out of fifteen science lecturers given 5 minutes
each to teach/perform in front of 2000 science teachers in The Music
Hall in Kansas City. While Don was onstage I forgot to be
nervous.
Dons props were a lightbulb a 2 Liter bottle and a loaf of
bread. He lifted the 2 Liter bottle up and lowered it down
continuously as he led the audience through a lesson on energy. He
demonstrated that he was doing 20 watts of work, and mentioned that
the work he was doing was enough to light a dim lightbulb. At that
point the lightbulb he was holding in his other hand began to glow.
The audience laughed.
He then switched to talking about density. Holding a loaf of
whitebread, he mentioned that there were two ways to increase its
density: increase its mass or decrease its volume. At that point he
threw the bread down onto a chair and sat on it producing a very flat
loaf of bread and a big laugh from the audience.
As Don came off the stage I shook his hand, he had done a great job.
Soon it would be my turn. Sooner than I thought actually, since
number 12 hadnt shown up for tonights performance.
The other competitors were a mixture of old pros and young
demonstrators. They included:the weird science guys, who reenacted
their infamous disappearing ink routine from the Letterman TV show,
Professor Science who set off explosions while roaming the stage in
marigold tights and a cape, Al Gunther who did an onstage version of
the Exploratoriums Magic Wand exhibit. Al waved white wands in
the air to reveal a projected image, Jenny Bird, a young local
science teacher from KATS (the Kansas area teachers of science who
were sponsoring the event) who did demonstrations with glowing
fluids, a guy who laid down on a bed of nails while students used
sledge hammers to break cinderblocks on his chest, and a woman who
did demonstrations using liquid nitrogen.
Steve Jacobs the Master of Ceremonies introduced me: Paul
Doherty from the Exploratorium will play the worlds largest
whirly. I walked onstage following two stagehands who carried
my table full of whirlies. I stopped in the center of the large stage
a few feet back from the gaping maw of the orchestra pit. Looking
out, I was shocked to see nothing but blackness outside the glare of
the footlights. The stage hands had forgotten to turn on the house
lights after dimming them for Al Gunther. So I performed to the few
people I could see in the front row.
Before I play the giant whirly, I said, let me give
you a capsule history of whirled music. I paused hoping the
audience would catch my double meaning... I waited for what seemed an
eternity before someone laughed, that triggered the rest of the
audience into laughter. I was still nervous but the laugh made me
feel better.
I twirled the three foot long childrens toy whirly playing a
series of notes up and down the scale. I fell in love with the
sounds of the whirly the first time I heard one. Whirlies only play
notes which sound good together,I added, in addition, in
the era of shrinking school budgets the whirly lets me combine
physics class and music class &emdash; after all, the whirly is an
example of quantum theory &emdash; no matter how I swing it around,
it only plays certain notes. It does not slide from note to note it
jumps. It thus behaves like the electron in an atom which jumps
between energy levels. I got another, smaller, laugh.
After I had played the toy whirly for a while I got tired of
the same five notes and began looking for other corrugated singing
tubes. I conceived of a plan to incorporate the whirly into symphony
orchestras. That set me on a search for the full range of instruments
from alto to bass. My first experiments were geared toward finding
bass instruments.
I walked to the table and picked up a double length whirly made from
two regular whirlies taped together.
My initial experiments were partially successful.
I played the double whirly.
Note the lower pitch of the lowest note of the longer whirly.
The whirlies only sing sound waves which fit in them exactly, longer
tubes mean longer soundwaves which have lower pitch. Unfortunately,
the sound from this double whirly is too weak for this concert hall.
I despaired. Until, one day, my wife Ellen and I were at a friend's
swimming pool. In the pool I spotted a surface vacuum cleaner
trailing a long flexible corrugated hose. Ellen impressed me with her
speed as she stopped me from unfolding the blade of my knife. She
talked me into waiting a day and buying my own hose from a swimming
pool supply store.
"My friend Sarah Hopkins, a professional whirly player and composer,
tuned this piece of pool hose for me. She also composed the following
piece of music.
I played Deep Whirly Heartsong. The performance whirly filled the
hall with sound. As the last note faded away the audience applauded
and cheered.
Just like the Mr. Toad who was stricken with automobile fever,
I was smitten with whirlies. When I went to visit friends they hid
their china and lamps. The children loved me though.
One day a friend made the comment that my music was not very
multicultural. I took his words to heart.
I picked up a toy whirly attached to a 5 gallon plastic bag. I filled
the bag with air from a battery operated leaf blower. The audience
giggled at the sight of a turgid bag attached to a whirly, then
laughed aloud as I tucked the whirly under my arm and they figured
out what I was going to do. I played the bag whirly by squeezing the
bag under my arm.
After I played half a bagful of notes, I removed the bag from my
underarm and played the whirly in my usual swinging way. The whirly
sang and sucked the remaining air from the bag. The singing stopped
when the bag was empty. I looked quizzically at the quiet whirly and
its deflated bag and said, of course, pardon me but my
instrument seems to be a little flat tonight. (This time the
audience groaned.)
So I had found the whirly equivalent to the violin, cello, and
bagpipe whirlies but there were more whirly worlds to conquer. It got
to the point where my wife hated to go into hardware stores with me.
I kept blowing into and whirling every piece of corrugated hose I
could find; gas pipes, electrical conduit and electrical wire
guides... like these.
I picked up the two black "Fly" whirlies.
I was thrilled to find something to do with my left
hand.
I began to play Fly by arcing the two whirlies from above
my shoulders down across the front of my body.
When I play this I find that even in the roughest neighborhoods
no one gets within several feet of me. This motion allowed me to
combine music, physics and self-defense!
I segued into the second part of Fly which involves
swinging the two whirlies alternately, then into the finish with
arcing moves again. The audience applauded.
Whirly discoveries came fast and furious. I found my highest
pitched instrument in a 7-11.
I pick up a large plastic cup pull out the corrugated straw and blow
a few notes making high pitched sounds.
I still longed for deeper notes. Then one day at a winery my
attention was riveted by a piece of hosing. My wife shouted
NO! But she was too late I had found the Mount Everest of
whirlies &emdash; agricultural drain hose. It was three inches in
diameter and twelve feet long.
I picked up my giant whirly and held it, coiled around me on the
stage looking at it in a perplexed way.
The only problem was how could I play it? Then I figured it
out. It was a counter clockwise whirly.
I flipped it over. And gave a fiendish grin at the signer who was
standing beside me translating my performance for the deaf.
Clear! I shouted and she ran for cover.
Then I started to spin A loud low tone grew to fill the room. I spun
faster, a higher bass note rang out, faster and faster&emdash; the
whirly sang higher notes. I slowed down slowly, dropping from one
note to the next until I ended by holding the lowest note for a few
seconds before brining the whirly to a gentle landing on the stage
coiled at my feet. I ended facing the audience.
The room erupted with cheers and applause. WOW.
I walked offstage and was greeted by Don who shook my hand and said
that was fantastic.
We all received certificates designating us as Masters of the art of
science demonstration signed by the Director of the Royal Institution
of great Britain and by that famous Kansan, Don Herbert. But most of
all, I had fun playing the whirly in front of a great crowd.
The only problem was the fame. For the rest of the visit to Kansas
City people stopped me in the streets to ask about playing the
whirly. I needed to carry a self-defense whirly with me to keep the
crowds away.
