iPad 2 glass 27% thinner, yet stronger than original iPad?

Perhaps to save weight, the glass screen of the iPad 2 is 27% thinner than the glass screen on the original iPad yet this new test by iFixYouri shows it might be even stronger. Or to quote them:
“That glass was redonkulously strong!”
The increase in strength seems to come from greater flexibility. They performed a number of tests, including drops, without breaking the glass. Video after the break.
