Gleam, glitter, glow,

They're moving very slow,

Sometimes on a smooth surface,

Often searching they\'re way down,

Between hunderds of obstacles,

They can be seen in every town,

Always moving and searching their way,

Again and again, everyday,

They merge and seperate with their species all the time,

And they can also be found, in this little rhyme.

Two ducks before a duck, two ducks behind a duck, and a duck in de middle.

How many ducks are there?

Tim owns a pocket knife with five different tools. It has a corkscrew, a bottle opener, tweezers, a screwdriver and something else. What?
