  We simulate the quasi-static motion of a spherical particle through a stable,
horizontal soap film. The soap film subtends a fixed contact angle, in the
range $10-135^\circ$, where it meets the particle. The tension and pressure
forces acting on the particle are calculated in two cases: when the film is
held within a vertical cylinder, trapping a bubble but otherwise free to move
vertically, and when the outer rim of the film is held in a fixed circular wire
frame. Film deformation is greater in the second case, and the duration of the
interaction therefore increases, increasing the contact time between particle
and film. As the soap film returns towards its equilibrium shape following the
passage of the particle a small bubble is trapped for contact angles below a
threshold value of $90^\circ$. We show that this bubble is larger when the
particle is larger and when the contact angle is smaller.
