Splitscreen film of Rosie instructing you to hold your breath while simultaniously holding her breath underwater in the bathtub. You will have to hold your breath for:

–30sec
–1min
–1:30min
–2min
–2:30min
–3min
–3:30min
–4:00min

Oh yeah and we mixed some random exhaled breath holds in between to make it even more difficult ;)
