First week on the job and the new President was a no-show, he was out of town. Mr. Hogge filled in for Rick.
Guests:Ed Colucci, Carl Duncan’s guest AND Carl was here but failed to notice his guest was at the end of the lunch line until prodded by others in line.
Fines:Carl was fined $.25 for no badge, plus $.25 for neglecting his guest (who should have been sworn in by now).
Announcements: District Leadership Conference will be held this July 14 th from 7:30 – 12:00 noon at 7600 Orchard Road which is the Regis University South Campus.
Rees announced a couple golf tournaments coming up: Aug 10 Friends of Man and Aug 19 Meals on Wheels.
Enslow said the Annual Arapahoe Sertoma Fall Classic Golf Tournament is set for September 4 th, a Tuesday.
on’t expect this every week but I had a little contest to see who would be the first “member” to e-mail me, mentioning last weeks Newsletter. Bill Kohlmeier was the very first but he isn’t a member so the $1.00 went to Bob Stein who beat Bill Foerster by 4 hours. Bob received his reward in quarters.
Bingo Report: No Bingo, no report.
No SOD to allow more time for the program.
Program: Mabe Downey introduced Doug Hodous who has been a member of Littleton Sertoma for 10 years. Doug is a native of Colorado and graduated from CU. He was a school teacher at Littleton , teaching chemistry and science. With that background, Doug showed off some of the experiments he would do for his students. (Personal note: after Doug had all his equipment set up, I wasn’t sure if it was safe to sit in the front row).
Doug started off telling us an easy way to remember the names of the Great Lakes : H.O.M.E.S (you figure out the rest). Then he had a little poem, showing us a rock with some stuff on it. The poem is: Alice the algae is living with Freddie the fungus and lichen it, but their marriage is on the rocks (hint: algae and fungus produce lichen .
Doug showed us a better way to shoot rubber bands (kids, don’t try this without your parents supervision). Instead of just pulling the rubber band back, use your thumb to open it up, this causes the band to spin as it flies instead of thumbing or what ever a rubber band would do during it flight. He shot off a couple and they did seem to fly with more speed and he asked if we could see it spinning (of course we couldn’t, they were to fast).
Did you know diet cola floats and regular cola doesn’t? That is because regular cola as about 39 grams of sugar which is heavier then the sweetener in the diet cola so the can sinks in the tub of water. 39 grams of sugar is like using 39 of those little sugar packets. No wonder the kids are getting fat and getting sugar diabetes more.
Try this next time you go to the hardware store to buy a can of spray paint. Hold a magnet in your hand and shake the can until the magnet attracts the mettle ball inside, then tell the sales person that the can of paint isn’t any good because the ball inside the can that mixes the paint must be missing.
Doug held three different size metal pipes over a flame for a few seconds, then, when he pulled the pipe away from the flame, the heated pipe would cause air to rush through the pipe, causing a tone, depending on the size of the pipe. A smaller pipe, a higher pitched tone. (he didn’t say that there was a metal wire inside the pipe that was vibrating from the air flowing through but I did over hear him telling Mabe that he hasn’t figured out how this works).
He also demonstrated a couple tuning forks and the tone they produce when tapped but the most remarkable one was an aluminum rod, about ½” by 3’ long and after putting some stuff on his hand to cause friction, he would stroke the rod, causing it to vibrate. This was an example of how a violin string makes a sound after being excited by the horse hair on the bow.
Some other experiments were heating air in a sealed container, then sticking the end of the container in a glass of water and when the heated air started to cool down, it drew the water up into the container. (no, it didn’t SUCK the water up, this happens because of the atmospheric pressure which PUSHED the water from the glass into the container whose pressure had been reduced by heating the air (hot air is less dense the cooler air). Same with sticking a plunger against the wall. The air inside the cup has been pushed out so the atmospheric pressure is pushing the plunger against the wall. Once the pressure gets close to equalizing, the weight of the plunger will cause it to fall.
He demonstrated how a very fine powder like saw dust or dust from grinding corn or wheat will burn. He sprayed some dust over a match and it looked as if the fuel was a liquid and not a powder. That is why grain elevators blow up, the dust in the air is ignited by a spark and CABOOOOOM.
Thanks Doug, good show.
