Propellers for STEM Projects | Thirty plastic propellers for rubber band helicopters, planes, cars, and classroom STEM builds : Toys & Games Review: They work! - I was pleased with these. Used them in a STEM event at local primary school in the UK - the kids loved them. Younger children will need some time practicing winding them up before launching. Review: Validated in Educational Use - These 6-inch plastic propellers were utilized as the primary rotational component in a youth engineering activity involving gravity-assisted zipline racers. In this application, the propellers were subjected to repeated cycles of acceleration, deceleration, impact loading, and thermal exposure typical of extended outdoor instructional environments. Performance remained consistently stable. Blade integrity was maintained, rotational balance was adequate for sustained use, and no material fatigue or structural deformation was observed across multiple iterations and participants. Importantly, the propellers demonstrated a resilience well beyond what is often assumed for lightweight injection-molded components used in educational settings. Based on observed outcomes, these propellers are well-suited for hands-on STEM instruction where durability, repeatability, and safety under enthusiastic use are essential. ## Features - Designed for STEM Projects: This bulk 30-pack of 6-inch, 2-blade plastic propellers is specifically engineered for rubber band-powered creations, including airplanes, helicopters, ziplines, and propeller-driven cars. - Easy for Kids to Use: The propeller assembly mounts securely onto standard craft sticks, popsicle sticks, or balsa wood measuring up to 0.135 by 0.35 inches, providing a reliable foundation for building. - Directional Thrust Control: Featuring a built-in propeller shaft with a small hook for rubber bands, the design only permits winding in one direction. This ensures the generated thrust consistently moves your project forward. - Adjustable Performance: The propellers generate substantial lift and thrust. Builders can use a single rubber band for a slower, sustained energy release, or double the rubber bands for a quicker, more powerful burst of energy. - Durable Materials: Constructed with high-quality steel and semi-flexible plastic. The plastic blades are resilient enough to withstand minor to moderate impacts, while the steel shaft resists bending during normal use. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07792XL3X | | Best Sellers Rank | #113,917 in Toys & Games ( See Top 100 in Toys & Games ) #139 in RC Vehicle Propellers | | Brand Name | STEM Inventions | | Color | Black | | Customer Reviews | 4.2 out of 5 stars 136 Reviews | | Educational Objective | Teach and reinforce scientific and engineering concepts | | Manufacturer | STEM Inventions | | Manufacturer Maximum Age (MONTHS) | 144 | | Material Type | Plastic, Steel | | Operation Mode | Manual | | Power Source | hand-powered | | Set Name | 30pcs | | Supported Battery Types | No batteries required | | Theme | Christmas | | UPC | 728028461862 | | Unit Count | 30 Count | ## Images ![Plastic Propellers, 30-Pack - Bulk 6 in.

Used them in a STEM event at local primary school in the UK - the kids loved them. Younger children will need some time practicing winding them up before launching. ### ⭐⭐⭐⭐⭐ Validated in Educational Use *by B***K on December 21, 2025* These 6-inch plastic propellers were utilized as the primary rotational component in a youth engineering activity involving gravity-assisted zipline racers. In this application, the propellers were subjected to repeated cycles of acceleration, deceleration, impact loading, and thermal exposure typical of extended outdoor instructional environments. Performance remained consistently stable. Blade integrity was maintained, rotational balance was adequate for sustained use, and no material fatigue or structural deformation was observed across multiple iterations and participants. Importantly, the propellers demonstrated a resilience well beyond what is often assumed for lightweight injection-molded components used in educational settings. Based on observed outcomes, these propellers are well-suited for hands-on STEM instruction where durability, repeatability, and safety under enthusiastic use are essential. ### ⭐⭐⭐⭐ Way Overpriced *by B***0 on September 7, 2022* These are great, but need to cost less. Unit cost of manufacture is a fraction of a penny. Teachers and schools use these for STEM lessons where the student takes it home. Thus, it is a one use lesson that needs craft sticks, card stock, rubber bands, and paperclips to be complete. These need to cost way less than a dollar per student. ## Frequently Bought Together - 6-Inch Plastic Propellers, 30-Pack – Build Rubber Band Powered Planes, Helicopters, and Projects - Mounts onto Craft Sticks or Balsa Wood - Toy Wheels - Bulk Pack of 100 - Small Plastic Wheels for Toy Cars, STEM Projects, Crafts, Mini Vehicles - Wooden Blocks for Crafts, 200 Pack – 1/2 Inch Wooden Blocks for Crafts and DIY Projects, Unfinished Wood Cubes, Counting Cubes for Kids, Makers, and Classrooms --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/56636508-plastic-propellers-30-pack-bulk-6-in-propellers-for-stem](https://www.desertcart.us/products/56636508-plastic-propellers-30-pack-bulk-6-in-propellers-for-stem) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-26*
