What Cristine did was use our Blicket Detectors. And what she did was show children that yellow ones made it go and red ones didn't, and then she showed them an anomaly.
Cristina a utilizat detectoarele Blicket si le-a aratat copiilor cum cele galbene se pun miscare, in timp ce cele rosii nu functioneaza dupa care le-a aratat o anomalie.
