We're going to show babies a box of blue and yellow balls, and my then-graduate student, now colleague at Stanford, Hyowon Gweon, is going to pull three blue balls in a row out of this box, and when she pulls those balls out, she's going to squeeze them, and the balls are going to squeak.
Les mostraremos una caja de bolas de color azul y amarillo, y mi entonces estudiante de posgrado, ahora colega en Stanford, Hyowon Gweon, sacará tres bolas de color azul en fila de esta caja, y al sacar esas bolas fuera, las apretará, y las bolas chirriarán.
