That's my 65 year old childhood toy in my village. same construction. mine is simpler. functions as a catapult or bow. • on the body there is a place to put catapult seeds. without picking up, just slide the valve at the top - with the upper back of the valve as a runway - a seed trench and as a darts runway. slightly lift the front body. The seed rises from its place and slides backwards into the throwing net, catch and aim and then release. • Likewise if you want to shoot archery. put it on the runway along the body, put pinch, aim and release. • material completely from bamboo. use a knife to cut, slash and grind just like making a kite
if you are a boy this is an idea for a great toy. if you are a father, you absolutely do not want your son to come up with something like this, because it will mean very big trouble.
If you want a REALLY powerful slingshot, one strong enough to kill, buy a Wrist Rocket. Not just a pretty name.
Why do I get the feeling there are some children crying at a birthday party because he took their balloons?
