Male giraffes fight each other by 'necking'! They push their long necks against each other, bending and twisting them in order to win the fight by a show of strength. Many animals fight this way, including snakes, insects and crabs. Competing in this way allows animals to find out who's boss while protecting themselves from injury. The strongest wins and the loser just has to go away.
This car runs on air...imagine!
This car runs on air...imagine! Guy Negre, the former Formula 1 race-car engineer,
has invented a car that uses nothing but compressed air for power.
The "E.volution" costs less than 1 cent a kilometre to operate and
can reach a speed of up to 130 km/h. The car runs out of power
after about 200 kilometres, but it can be plugged in for a few
hours to recharge the air tanks. The first batch of air cars will
be built and sold in France later on this year. Nineteen other
factories around the world will also build the air car in the near
future. OCTOBER 27, 2000
