This is a really powerful recorder gun recorder being the instrument, and can easily be taken apart and turned back into an instrument.

Step 1: Materials

You will nedd only these three things:

A full Tudor Recorder set
A Large rubber band
A small1 inch long peice of paper

From the recorder set you will need: The recorder and the cleaning rod.

Step 2: Inserting the Rubber Band

Take of the top of your recorder (the part you blow into). You should probably put the rubber band through the back hole (B) because that one's larger.
to insert it you pinch the two sides of the rubber band together (Picture 2) and push through the hole. Then, stick the cleaning rod through the bottom up the rubber band and use that to push rubber band through top. You want to leave about 1/2 an inch of the rubber band sticking out the B hole.

Step 3: The Paper

Just roll up the paper and stick it through the loop coming out of the B-hole and pull rubber band taught from top.

Step 4: Finishing and Firing

Now, to finish it off, fit the rubber band around to the bottom where the recorder sort of branches out, loop it around that and you done! Now, to fire all you do is insert the cleaner or anything else that will fit, in through the top, pull back, and release! This may be capable of causing injury or damage, I will not take responsibility for either.
