Silly puddy reflection

When we started the silly puddy experiment i noticed that u had to keep adding either baking powder, water, glue or acid. I had noticed that my silly puddy came out of the cup just fine because i added the right amount of ingredients to make it, as i looked at the others in class, i noticed several having trouble, some asked me how i got it out and i said i just added more acid. I like how the ingredients interact with each other and make the silly puddy, but i was sacred that i would forget to was my hands after playing with it, because Mrs. L had said you could get a stomach ake if you don't wash your hands and put it in your mouth. I liked this experiment because we got to keep the silly puddy afterwards. :)

San Diego's Ocean Glows In The Dark!



The oceans surrounding the coastal of San Diego, California are know as warm, crystal clear. People have noticed that there are blue electrifying streaks that light up the oceans at night, it is not a sign of aliens landing but a phenomenon called Red Tides, which occurs along the California coast and many other part in the world. This only happens when a certain species of a tiny microscopic organism known as phytoplankton becomes dominated with the ocean. These tiny organisms don't light up during the day. In the day they make the blue ocean waters into a very murky red, brown or purple color. However in the night the water becomes magical with their electrifying blue flashes of light that are causes by a chemical reaction when the cells hit against something. However these organisms are not terribly toxic which means that you can actually swim in the glow-in-the-dark water.
