Suppose you are playing ice hockey in the middle of a totally frictionless frozen pond. How can you move yourself to the edge of the pond? Explain what you would do and why it would work.

Throw your hockey gear forward and you will move back. Conservation of momentum says momentum of system remains zero.
So
equipment mass times its speed forward = your mass times your speed backward
