It's simulator called the Mommy Tummy. Warm water is pumped into a plastic bag that expands by the minute. Four-dozen balloons inflate and deflate, to mimic the kicking and movements of a fetus.
The device takes you from normal to full term in two minutes. The inventors hope it can give dads-to-be a better idea of what pregnancy does to a woman for months. That's even without the morning sickness, stretch marks and cravings.
