  The Taffy Galaxies system, UGC 12914/5, contains huge amounts of molecular
gas in the bridge region between the receding spirals after a direct collision.
$2 - 9 \times 10^9$M$_\odot$ of molecular gas is present between the galaxies,
more than the CO emission from the entire Milky Way! Such dense gas can only be
torn off by collisions between dense clouds, in this case with relative
velocities of about 800 $\kms$, such that the remnant cloud acquires an
intermediate velocity and is left in the bridge after separation of the
colliding galaxies. We suggest that after ionization in the collision front,
the gas cooled and recombined very quickly such that the density remained high
and the gas left the colliding disks in molecular form.
