What is the simple way to make a slingshot?

1. Slingshot control system: made of wood. Go to the countryside and look for a tree branch in the shape of a "human", which should be uniform in thickness, with no broken lines or scars, and about 15 centimeters in length.

2. Slingshot power system: The first choice is rubber strips with high strength, high toughness and high elasticity. You can also choose cow leg ligaments made by special technology. Length is about 40 cm, two pieces.

3. Slingshot ammunition launching system: Use tanned cowhide, cut it into a rectangle of 3*8 cm, and cut a small hole at each end in the length direction that can accommodate the power system.

4. Assembly: Fix the power system on the small holes of the launch system, one for each hole, remember to be firm; the other end of the power system is fixed on the two "human" forks of the control system The top of the fork must of course be firm. Also note that the two power systems must be of equal length. The assembly is now complete.

5. Ammunition: Steel balls with a diameter of about 1 cm are preferred, followed by round stones with a diameter of about 1.5 cm. From the perspective of lethality, steel balls are more ideal.
