Video Description

"This week on Smosh Lab - a magical bag that won't pop?!"


Shayne and Nick poke pencils through a plastic bag to prove the strength of plastic and the pressure of water.

They then do the same to a giant water bag, finding similar results.


For unknown reasons, this episode is not considered 'episode 18' on the official Smosh Lab playlist, with SLOW MO SLINKY DROP W/ VERITASIUM being considered the true 18th episode.
