If you want to know how to make a bamboo bow and arrow here are the steps:
Bow
1: Cut down a stalk of bamboo about 1.5 cm. wide then partially cut off the branches but leave a stub in the middle.
2: Cut that to around 1 meter, what Ever is comfortable for you make shure to cut it a centameter beyond the last ring on both sides.
3: Then put a bunjee cord hook in the ends of the bamboo and you have got your bow.
Arrow
1: Cut a 1 cm thick 2ft. Long piece of bamboo with the leftover bamboo.
To tweak the bow so the arrow does not scrape your hands you need to cut a Y shaped branch 2 in. Long then secure it on the stub on the bow with rope or twine as a notch for the arrow. Sharpen the arrow if you want to. The picture above shows how the bow should look when you are finished.
Pay attention to how you hold the arrow.
