  You can also blow your hands off, blind yourself and/or burn down the building. So be very careful if you try this. Note it is illegal to make your own solid fuel motors in some countries (you need a special license in the UK).

    Of course yeah, not just dangerous but as you said it can be illegal, so always double check the laws or get the needed permits.
