This video shows various experiments with circular motion. In Dr. Carlson's Science theater he uses water, a lit candle, and a piece of paper to show the ways that circular motion causes gravitational pull. The water in a glass doesn't spill as it is spun around 360 degrees in a circle, even upside down. The flame on the candle was pulled toward the center when spun around. The piece of paper becomes a paper saw and was able to cut wood when spun. He not only demonstrates centrifugal force wi...
Making a wooden spear requires a between medium and small thick stick, a rectangular piece of board, a hatchet and a wood clipper. The branches off the stick is removed and thrown away. The stick is clipped at the smaller end.

There is a reason the Amanita phalloides mushroom is called the "Death Cap." It can kill you. Mushrooms are a type of fungi, an organism that produces thread-like mycelia that often produce spores. Spores allow the fungi to reproduce. Molds, lichens, and yeast are all fungi, but the most visible fungi are mushrooms. Some fungi are delicious, but others can cause disease or, and still others, like Penicillium, can cure it.
