Party Activities... Wounds
You will need:
* Petroleum jelly
* Red food colouring
* Cocoa powder
* Disposable tissue
* Bowl
* Cotton wood buds
What to do:
1. Use a cotton wood bud to mix 3-4 drops of red food colouring into a dollop of petroleum jelly (e.g., Vaseline).
2. Stir in enough cocoa (a pinch or so) to darken the red colour to a deeper, blood-like tint.
3. Separate the tissue and tear out a small rectangle (3x2 inches) from a single layer of the paper.
4. Place the tissue at the wound site and cover it with the petroleum jelly mixture.
5. Mould the tissue into a wound shape, with the edges raised higher than the centre of the wound.
6. Add some petroleum jelly mixture to the centre of the wound.
7. Sprinkle cocoa at the edges of the wound to darken it. Add cocoa to the wound centre if a scabby (as opposed to fresh) appearance is desired.
Note:
Red food colouring will stain, so avoid wound contact with clothing or furniture.
As soon as you cut yourself blood rushes to the site of the injury. You can see this if you scratch the underside of the your arm quite hard. The area you have just scratched turns red – this is the blood rushing to the scratched area.
Your blood contains many different types of cells: red blood cells that carry oxygen around the body, white blood cells that form part of your immune system, and platelets. When you cut yourself platelets form a clot by sticking to the site of the injury and to each other, stopping you bleeding and preventing germs from getting in.
