When young ghost Tara runs in front of Colin, the human older brother, while Colin and his dad are watching TV, Tara hits the bowl of popcorn on the coffee table and the bowl visibly moves. Earlier the film had established that ghosts would pass through anything solid unless they concentrated on that object to be moved. (In this case, Tara was not concentrating on the bowl.) Furthermore, the bowl had been in Colin's lap a moment before when it suddenly appeared on the coffee table. Immediately after Tara knocked the bowl aside, the bowl appeared back in Colin's lap in the next shot.
