Party Activities... Is it Slime? No it 'Snot!
You will need:
* Borax Powder
* White PVA glue
* Water
* Green and yellow food colouring
* Plastic Ziploc sandwich bags
What to do:
1. Stir 2 tablespoons of borax into 500 ml warm water. It's okay if some borax remains undissolved. Allow solution to cool to room temperature.
2. In a separate container, stir 2 spoonfuls of glue into 3 spoonfuls of water.
3. Stir a couple of drops of green food colouring into the glue mixture.
4. Pour into the plastic bag and add a spoonful of the borax solution. Squish the mixture around in the bag. Hey presto – you have made snot! Have fun!
Note:
1. A little yellow food colouring could be added for that extra sickly touch.
2. Don't eat or inhale the snot. Borax isn't toxic, but isn't good for you either.
3. Wash your hands after playing with your snot.
The scientific name for snot is mucus. Mucus is thick, slimy and gooey and it protects many parts of our body including the inside of our nose. Mucus is made of sugars and protein. Protein is what makes it so stretchy; it makes it sticky too.
We use it to trap all the dust, pollen and junk that's floating in the air. Sometimes when you blow your nose, out comes gross black stuff. It's usually mucus with trapped dust- otherwise known as …bogies!
