Kevin Delaney leads Jimmy Fallon and Lucy Liu in a series of science experiments on "The Tonight Show Starring Jimmy Fallon" on Nov. 7.

 

In case you missed it, Kevin Delaney may or may not be Thor.

Ok, so his mastery of thunder remains to be seen, but he definitely did have dominion over the clouds when he was once again featured on "The Tonight Show Starring Jimmy Fallon” this past Friday night.

His day job as the director of visitor experience for the Museum of Discovery caught NBC’s attention earlier this year, earning him a spot on the show. It turns out they just couldn’t stay away and had to bring back Delaney’s “Awesome Science,” much to Jimmy Fallon’s clear delight.

You can check out the video of his appearance below where they explore different densities of gasses. Even Lucy Liu gets in on the fun.

And now we all want to be Delaney's best friend.
