Pulley can prove that simple machine changes the direction of effort.
when you use less force to move an object

It is a device that can store elastic energy. It is not a machine, which changes force and distance and/or direction.
A simple machine is mechanical device that is non-powered. It changes the direction of a force. Some examples of a simple machine include a wheel and axle, a wedge, and a pulley.

An inclined plane (ramp).
An axel is a simple machine that relies on change in direction to make work easier. Furthermore, a simple machine is a device that makes work easier by increasing force or changing the direction of a force without electricity or other power sources.
A simple machine is a type of machine that changes forces in some way, by amplifying them, and/or changing their direction. The lever, the pulley, the wheel and axle are all simple machines. But there are complex machines as well, which do far more things. Our computers are also machines.
simple machines like pulley, liver and fulcrum.

A straw is not a simple machine. Simple machines are mechanical devices that change the direction of a force. A straw does not redirect the direction of the force.
