A small
rocket made using paper matches, aluminum foil and a needle.
To create, take one paper match and hold the needle against the
flat side of the match making sure that it is touching the sulpher portion of the match (the head).
Then wrap the head and a
bit of the body of the match with a piece of aluminum foil (about half an inch) making sure to wrap it tightly.
Remove the needle from the wrapped match so that there is an exhaust system of sorts molded into the foil.
Light the
rocket with another match by holding it underneath the foil until the
rocket ignites. The "pocket rocket" will shoot forward, propelled by the
gas escaping backwards through the exhaust hole. A bent paper clip makes a decent launch pad.
