Propellers for STEM Projects | Ten plastic propellers for rubber band helicopters, planes, cars, and classroom STEM builds: Propellers - desertcart.com βœ“ FREE DELIVERY possible on eligible purchases ## Features - Designed for STEM Projects: This 10-pack of 6-inch plastic propellers is specifically engineered for rubber band-powered creations, including model airplanes, helicopters, and propeller-driven cars. - Easy 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 | B06X3Q8C24 | | Age Range Description | Kid | | Battery Description | No batteries required | | Best Sellers Rank | #193,449 in Toys & Games ( See Top 100 in Toys & Games ) #337 in RC Vehicle Propellers | | Brand Name | STEM Inventions | | Customer Reviews | 4.2 4.2 out of 5 stars (170) | | Educational Objective | STEM | | Item Dimensions | 7.01 x 2.99 x 0.98 inches | | Item Weight | 4.54 g | | Manufacturer | STEM Inventions | | Manufacturer Maximum Age (MONTHS) | 120 | | Manufacturer Part Number | 43234-1307 | | Material Type | Plastic | | Model Number | 43234-1307 | | Set Name | 1 set | | Size | Small | | Theme | Vehicle | | UPC | 631912022363 | | Unit Count | 10 Count | ## Images ![Plastic Propellers, 10-Pack - 6 in.
