I give you the pine-cone . . . It comes in several shapes, it is sticky, prickly and pointy, but what else you ask is cool about Pine-cones? These photos now click the like button or else!
Believe it or not I am actually allergic to the pine pitch/sap if it gets on my hands or skin I puff up like one of those balloons in the Christmas day parades... hey gang look there is Snoopy, oh wow here comes Garfield and WTF look it's a fat old guy and he is sort of turning blue!
And with that yes, I still feel the need to play with them, something else pine-cones are good for is fire starter, trust me that is why I collect them fast fire starter and in the winter at camp you just need 2 of those little sticky bastards to start the warm fire.
