How are glass items packed for transportation using a bubble wrap or hay protected from damage? [Pg. No. 106]

Bubble wrap and hay protect glass by compressing upon impact, which increases the time taken for the glass to stop. According to Newton's Second Law

$$\left( F \propto \frac{\text{Change in momentum}}{\text{time}} \right)$$, increasing this time drastically reduces the impact force. Additionally, the tight packing overcomes inertia, keeping the items firmly in place so they don't collide.
