Slingshot Materials: What's It Made Of?

Slingshot (Catapult) Construction Materials

A slingshot is a simple projectile launcher consisting of a frame, elastic bands, and a pouch.

Frame

• Traditional: Y-shaped fork from hardwood (oak, hickory, ash, dogwood) — natural grain resists splitting.
• Modern: Aluminum, stainless steel, titanium, fiberglass-reinforced polymer, carbon fiber. Ergonomic grips, wrist braces (wrist-rocket style).
• DIY: PVC, wire coat hanger, antler, bone.

Elastic Bands (Power Source)

• Latex rubber tubing: Surgical/therapy grade (TheraBand Gold/Silver/Black) — consistent taper, high energy return.
• Flat latex bands: Cut from sheet latex; adjustable width/length.
• Synthetic elastomers: TPU, silicone — temperature stable, latex-free.
• Configuration: Single loop, double loop, tube-through-pouch.

Pouch

• Leather (split cowhide, kangaroo — durable, grippy).
• Synthetic: Cordura, nylon webbing, rubberized fabric.
• Cradles projectile (steel ball, glass marble, clay, arrow).

Physics

Potential energy stored in stretched bands (Hooke's law region) → kinetic energy of projectile. Draw weight, draw length, band taper, pouch mass, and release technique determine velocity (often 150–300+ fps).

Safety: Eye protection mandatory. Treat as weapon. Check local laws (some classify as weapon).
