Plastic Propellers, 10-Pack - 6 in. Rubber Band Propeller Kit, STEM | Ten plastic propellers for rubber band helicopters, planes, cars, and classroom STEM builds

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

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.

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 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.

Our 4th grade kiddos made propeller cars this year and these worked much better than the ones we had.

They served there purpose

These propellers worked perfectly for our rubberband helicopter camp craft! Great quality and easy to use.

Easily broken. If you put them on the front of a plane they will break upon landing… which defeats the point. It cannot be super glued or fixed, which is an even bigger bummer because the fracture plane is inevitable, it works great for the first 30 seconds though!

Bought for Beaver craft activity, task was to make a flying machine. All were in good condition on arrival. They fit nicely onto standard lollipop sticks (got 50 pack of wooden ones from wilcos for £1). I also bought some sellotape, elastic bands and paperclips (to loop elastic bands round to at the bottom) for this activity so that the helicopter design could be made easily. Overall the quality of these is good, they were loaded with high tension from many elastic bands, thrown around and smashed into things as they flew, but none of them broke. Due to the cost, (~£13 for 10) we will be re-using them (rather than letting the kids take them home) so they have been a worth while investment for the group. I would recommend these.
