Smosh Lab is a show on Smosh Pit (formerly Smosh 2nd Channel) created for Smoshtober. It premiered on October 5, 2016 with the episode Smashing Stuff with Science! and stars Shayne Topp together with Nick Uhas from Nickipedia as hosts.
In every episode, the pair of Topp and Uhas recreate different science experiments by themselves or sometimes with invited guests.
Even though it was supposedly created for Smoshtober, Shayne stated in the comments that if people like it enough it could continue afterwards.
The show is paused for now after Shayne announced it on its finale episode. This pause comes exactly 1 year after its debut.
