  You will need
:-  A clear drinking glass (1 pint), Bowl of water (washing up bowl or sink), a cork (get mum or dad to drink a bottle of wine first!)

  Instructions :-
Float the cork on the water's surface.
Hold the glass above the floating cork.
Press the open mouth of the glass down into the water above the cork.

PREDICTION:-
What do you think will happen to the cork?

Here is the hard bit....
 
Can you explain why it happened?
 
Good Luck - please add your results as a comment on this Geog Blog
