A scrim will appear entirely opaque if everything behind it is unlit and the scrim itself is grazed by light from the sides or from above. A scrim will appear nearly transparent if a scene behind it is lit, but there is no light on the scrim. A dreamy or foggy look can be achieved by lighting a scene entirely behind a scrim.
Food or small objects can cause choking if they get caught in your throat and block your airway. This keeps oxygen from getting to your lungs and brain. If your brain goes without oxygen for more than four minutes, you could have brain damage or die. Read more on MedlinePlus.gov.
In children, choking is often caused by chewing food incompletely, attempting to eat large pieces of food or too much food at one time, or eating hard candy. Children also put small objects in their mouths, which may become lodged in their throat. Nuts, pins, marbles, or coins, for example, create a choking hazard.
