A lot of holiday gifts are fragile.
But some are more precious than others, so a lot of companies test their packages for durability.
Here's a behind-the-scenes look at how FedEx — which ships 25 million boxes daily during the holidays — gives its boxes a beating.
Boxes are intentionally dropped from various heights to simulate forces experienced during sorting.
And we all know sorting is the real Grinch of shipping and handling.
Worried your box may get crushed?
The company conducts compression tests to ensure its boxes withstand the pressure.
FedEx even does a vibration test to see how boxes will fare on a plane or in the back of a truck.
We're still waiting for the package polka-resistance test.
