Why do we sneeze?
« on: 21/04/2016 22:50:01 »
Mlilo asked the Naked Scientists:
   1.What biological phenomenon is sneezing?
2.Why do human beings, sheep and goats sneeze and other animals do not?
3.Under what circumstances does a cocktail lay an egg? (An egg of a cocktail is almost the size of a pigeon's egg but only contains the egg white and no yellow. )
What do you think?
