Something a little different, laughter yoga
(youtu.be)
Theres a good 30 seconds of laughs before they move on.
I'd like to try this myself sometime I think.
Apparently some laughter yoga places have call in lines, where you can join in and start laughing. I don't think it has any spiritual benefits, but it's probably fun.
A place to submit videos of people laughing contagiously.
