Find someone to teach me how to make A Mu tea slingshot.

Mu Cha slingshot material: a V-shaped Mu Cha. Two rubber bands. Pack one. Material requirements: The V-shaped Mu Cha is about two and a half inches wide, two inches thick and thumb thick. The total length of the Mu Cha is about six inches. See what you like! The rubber band is 2-3 cm wide, and the greater the tensile elasticity, the better. It is best to choose a small pebble with cowhide material size that can cover the size of the little finger. Specific practice: Fix the rubber belt at the head end of the V-shaped Mu Cha. It is best to cut a two-centimeter-deep groove at both ends of the V-shaped Mu Cha, and connect the other end with the bullet bag. Cut two small holes on both sides of the elastic bag with scissors, as long as they can pass through the belt. It is best to tie the four ends with a thin and strong rope! Ok, a beautiful slingshot will come out! ! I hope it can be adopted! !
