The interaction at 2:08 is so funny to me
- "Did the floor explode?"
- "Hahaha... yeah"

I am a plastic research guy... Generally, most of the plastics that we use in our daily household or workplace have flexibility at room temperature. Some plastics like PP, HDPE also has crystallinity due to which they are tough and long lasting.
Coming to flexibility of these plastic container/buckets/treys, it comes from their segmental mobility upon stretching. When such plastics were kept frozen for long time in a deep freezer they tend to become too hard and lose their flexibility due to a lack of segmental mobility. When it comes to pouring liquid nitrogen into those buckets you are instantly freezing the polymer chains and they are becoming a glassy material at cryogenic temperature eventually breaking. This is a very good demonstration for students as well, particularly to explain why you should not use a plastic cup to take liquid nitrogen.

some experiments involve detailed planning, rigorous experimentation, and peer review from multiple colleagues
other experiments involve pouring a bunch of liquid nitrogen on the floor and saying "yep, floor broke"
