6-Inch Plastic Propellers, 30-Pack – Build Rubber Band Powered Planes, Helicopters, and Projects - Mounts onto Craft Sticks or Balsa Wood

Bought to make a school project. They fit perfectly on a popsicle stick. And worked perfect.they are very durable .Will buy again.

These were so much fun to use in a class about flight. They fit well on popsicle sticks and the kids were able to send them all the way to the ceiling. Would definitely recommend.

I used these propellers to make helicopters with kids. When they didn’t break they worked awesome. I found if you put a lot of tension on the rubber band the propeller would snap between post and hooks holding piece. Also, the fit on a popsicle stick is pretty snug which is great to ensure it stays on but it also has broke on me because I put too much force on the wrong part of the prop. So, as long as it is not overwound and your careful placing on the stick then these are a great deal. The really do work well and made the helicopters fly far. I made 1 rubber band plane and it flew better than a store bought. I would buy these again.

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.

The propellers worked great for our Girl Scout event. They were sturdy and easy for all the girls (ages 5-11) to use with minimal adult help. They all loved making rubber band helicopters.

My grandkids had a great time this summer making helicopters that actually go pretty high! The propeller just snaps onto a popsicle stick. The only other supplies you need to make a helicopter are: rubber band, paper clip, tape, and construction paper. There are several YouTube videos out there on how to do this. After a few trial and errors, my six-year old made some helicopters that went at least three stories.

The media could not be loaded. Do not fly

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.
