BASE jumping is an extremely
dangerous activity. A lot of BASE
jumpers die every year. BASE
jumpers jump off tall buildings,
bridges and mountains. They've got
a small parachute on their backs.
They fall very quickly, so it's
important to open the parachute
very fast! They haven't got much
time to use the parachute before
they hit the ground.
