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.
Signs and Symptoms of Choking. A child who is choking often appears panicked and may wave his or her arms or grab at his or her throat. Older children may hold the neck with one or both hands, which is the universal sign for choking. Signs and symptoms of choking include struggling to breathe (gasping), coughing, gagging, and bluish lips or skin. If a choking child can cry, speak, or cough forcibly, the airway is partially blocked.
