Beware, children of Earth ... if you dare to get on a basketball court with James Harden you might go viral ... 'cause the Rockets star just totally put a kid in the popcorn machine and it's all on video.
It all went down and Harden's basketball camp where he went 1-on-1 with a kid and probably made the tyke's whole summer.
Check out the clip ... Harden gives him a little shake, a little bake, and a BIG fake ... the finishes the whole thing with a dunk.
Not quite Kevin Durant level child dominance .
