Since you did not specific how well the poppers had to be made, I will show these. I give away more popper than I use because I tend to favor flies with a little less air resistance. All but the black one are foam, its balsa, the white bug with on the back right ( from the face side) is made from old Nike running shoes, the rest from flip flops.
