  Facts
  • Your body makes this sticky mucus for a very special reason.
  • The air we breathe isnít always as pure and clean as we might like it to be - sometimes it has things like dust, smoke and germs in it.
  • The mucus lines your nose and helps to trap the stuff that shouldnít be in the air to stop it from getting into your lungs.
 
  Did You Know?
  • Every time you breathe air in and oxygen out itís helping to dry out your nose mucus to make crusty bogies.
  • If youíve been in a smoky or dusty place your bogies can take on the colour of that dust because of all the dust the mucus has trapped.
  • Your body makes a fresh batch of mucus about every half hour.
  • You swallow mucus every day - it trickles down the back of your throat into your stomach.
  • Your stomach also has itís own lining of mucus - this mucus is very important because you stomach contains hydrochloric (high-drow-claw-ric) acid which is so powerful it can eat through metal. The mucus in your stomach protects your stomach lining from the acid.
 
  Experiments
On a windy day spread a little glue onto a sheet of thick paper or cardboard and take it outside. Have someone hold the paper while you shake the doormat beside it. The wind will carry dust particles past the paper and the glue will trap any of the dust that touches it - just like the mucus in your nose traps the dust in the air you breath.
