Human skin is opaque - in that it lets a small amount of light pass through (like looking at a light through a sheet of white paper). The red colour comes from the minute blood vessels illuminated by the light passing through the skin.
The flashlight shape is always in tube body, which is easier to held by hand and put in batteries.
Yes it is. If you put a activated glow stick in hot water the atoms in a glow stick will start to move around. The plastic will expand letting the atoms move. When the atoms move they create energy, energy equals bright light. If you were to put the activated glow stick in room temperature water it would not be as bright. The atoms will stay the same. If you were to put a activated glow stick in cold water the atoms won't move. They will huddle together. No movement means no energy which means no brightness. You are welcome :)
No, placing a glow stick in the freezer will not make it last longer. In fact, extreme cold can affect the chemicals inside the glow stick and may cause it to dim or stop glowing altogether. It's best to store glow sticks at room temperature for optimal performance.
One pair of forces is your hand pushing against the wind, and the wind pushing back against your hand.Another pair of forces is gravity from Earth pulling your hand down, and your hand pulling up against Earth; but this doesn't depend on the fact that the car is moving.
When a glow stick breaks open on your clothes, the chemical inside can stain the fabric. The stain may be difficult to remove, especially if the fabric is porous or delicate. It's best to wash the affected clothing as soon as possible to minimize the staining.
