How can a slingshot aim at the target?

The slingshot should aim at the target with the same force to form a three-point line.

1, the force is consistent, and the force is concentrated, that is, when pulling the slingshot, the elastic body should be placed in the middle position as the stretching point, that is to say, the rubber bands on both sides have the same force and are concentrated in the middle elastic body.

2. Form a three-point line, that is, the eyes and the projectile should form a line with the target point, which requires that the hand pulling the projectile should be on the same horizontal line with the slingshot, the hand holding the rod should be perpendicular to the rubber band, the aiming should be steady, the hand should not shake, and the pulling force should be balanced.

3. After aiming at the position, the projectile should be launched quickly, that is, let go quickly. Otherwise, you may miss your goal because of lack of concentration, but you will go astray and hurt your hand.

Slingshot production materials:

1, the production of wooden slingshots: generally made of tree forks on willow trees. Choose the right fork. When you stop your hand on the fork, you can see that it is an isosceles triangle. Pay attention to leave more space when cutting to avoid cutting, so as not to waste. Remove the skin from the cut fork and dry it naturally. Don't put it in the sun, because exposure will crack the skin. Set the shape and twist it, which is the kind of wooden screw with a ring, and a wooden slingshot frame will be ready.

2, the production of iron slingshot frame: If you have never seen a slingshot made of wire, it is necessary to teach it face to face, which is more complicated.

3, rubber band: generally use the kind of bicycle tire valve core, buy 4, each cut into two pieces of the same length. You can use the bladder if you can.

4, elastic pocket: you can go to the place where shoes are repaired and buy the best cowhide.
