You might be worrying what happens to the baby once sufficient centrifugal force is applied. Don't worry, it doesn't go flying across the room! There's a net to catch it. There's even a little bit of cotton wadding to prevent it being slammed into any machinery.
The net still raises unpleasant questions as a newborn baby's skull bones aren't fused yet so being accelerated into a net probably isn't good for its head.
Also, the Blonskys don't tell us what's supposed to happen to the placenta. Does it slam straight into the baby from behind?
