Classes begin tomorrow? Where did the summer go?
September 2, 2009 – 5:10 amI could use another week of Atlantic City, NJ. The surf off of the Chelsea Ave. beach was stellar, and I want more.
The torrential rains of two days filled the area between the boardwalk and dunes with brackish pools. The wind whipped waves moving from the left of a walkway found only a one foot gap to get by, and on the sheltered side on the right, formed an enormous single slit water wave experiment. Beautiful. Alas, I was running and had no camera.
At least there are demonstrations to do tomorrow. For Life and Physical Sciences A, at 9 am:
Green balloon with helium. Blue balloon with hydrogen. Candle on end of stick, matches to light.
Plus liquid N2, soda bottle and trash can.
Also, some elements : Sulfur, Copper wire and copper powder and copper bar, Zinc, halfnium, germanium. And some cupric chloride. Is there any way I could test the conducitivity of these materials?
Off to make the demos.
