“Give it here,” Harry called, “or I’ll knock you off that broom!”
“Oh, yeah? […] Catch it if you can, then!” he [Malfoy] shouted, and he threw the glass ball high into the air and streaked back toward the ground.
… A foot from the ground he [Harry] caught it, just in time to pull his broom straight, and he toppled gently onto the grass with the Remembrall clutched safely in his fist. – SS/PS.
