We hear in the news almost every day of some kind of technological or scientific advance. New technologies like genetic engineering and nanotechnology are giving us the power to remake the world already. But should we be concerned about these advancements? Will this eventually lead to a dangerous dependence of technology?

Describe an experiment to test how chlorophyll absorbs certian wavelengths of sunlight, and yet doesn't absorb the bright green light.
Just an easy one would do.
I just can't think of one though.

Cleaning up after the Thanksgiving festivities, you have a bucket of ammonia solution in the kitchen. Your little cousin comes in and pours her glass of cranberry juice right into the bucket of ammonia. To everyone's surprise it turns from bright red to blue as it hits the ammonia.

Being an astute chemistry pro, what would your explanation for this curious observation be? Can you think of a way to really impress everyone by turning the solution from blue to red again?

the recipe is:
sausage
eggs
bread crumbs
celery
onions
butter

Cook sausage. Take out the sausage and leave the grease in the pan. Saute diced onions and celery in the leftover sausage grease. Melt butter in microwave. Beat the eggs in a bowl.

Pour melted butter over the bread crumbs which makes them moist. Combine bread crumbs, cooked sausage, beaten eggs, onions and celery and put inside the turkey. The turkey juices during the cooking process, flavors the dressing and makes it moist.
