Which is more powerful, pocket slingshots or ordinary slingshots?

Pocket slingshots are more powerful than traditional slingshots. Because the pocket slingshot is composed of a ring and an inverted cone-shaped rubber cylinder, when in use, projectiles such as steel balls or clay balls are stuffed into the bottom of the cone-shaped cylinder, and the rubber cylinder can be pulled hard to launch.

Merchants claim that the range is 100m, and the accurate range can reach 30 m. Tests show that pocket slingshots, as toys, do not meet the requirements of the fourth paragraph of the current national standard for children's toys.

Hazard analysis:

The projectile of pocket slingshot is steel ball or clay ball, which has a much larger range and a much smaller volume than traditional slingshots, and can be put into a pocket for easy carrying. Although the online seller's publicity shows that it is used for outdoor sports, its design is likely to be bought by children as toys, resulting in injuries.

Experiments show that the ejection kinetic energy per unit contact area of the pocket slingshot reaches 96.8 J/cm ㎡ under the tension of 60 N. According to the data of foreign research institutions, the ejection kinetic energy per unit contact area of the projectile exceeds 0.6 J/cm ㎡, which may cause serious eye injuries such as hyphema.
