Gavin: I don't want plastic in my eye.
[After a rat trap shatters a plastic pen].
Dan: Wow it hit me in the shoulder. You were right about needing safety goggles.

Gavin: Do you think that if you [wrapped rubber bands around] a human head, it would eventually cave it in.

Dan: Various explosions. I like that; "various explosions".

Dan: So if you're out exploring with your flint and steel, just grab the nearest can of petrol and there you go.

Gavin: Okay, how's this for a mental stat: The camera recorded for 5.1 seconds...
Gavin: ...and generated nineteen and a half hours of footage.
Dan: [pulls a face] I think I'm gonna be sick. That's disgraceful.
Gavin: Almost a day of footage.
Dan: That's vile.
Gavin: Do you think we should just stick it... like, put it on the second channel, as a whole video?
[Video annotation, linking to said footage: Oh no we didn't]
— From glass explosion
[After Gavin slows footage down to 120,000fps]
Dan: Has it stopped?
