Dragonfly Propellers - Camp Bundle of 48

My third-graders were launching these off their hands within minutes—the pack of 48 meant everyone got their own. The plastic is thin but surprisingly sturdy, and they really do spin fast enough to show lift.

I bought these for my daughter's science fair project on flight, and the variety of propeller designs kept her engaged for hours. The set of 48 is more than enough for multiple experiments.

My class has gone through almost the whole bundle already, and the four different propeller types keep the kids engaged in figuring out what makes each one spin differently. It’s a solid STEM kit that gets them thinking about flight without needing a lot of setup from me.
