Input wanted: slow motion ideas (Patreon)

Hi y'all! So a while ago I got a really cool slow motion camera and I've been experimenting/learning how to use it some in between videos. I think I am comfortable enough with it's use to maybe try one of the ideas I've had for it: SLOW MOTION LIVE! Basically the idea would be to do a live stream and the two of us take requests and input live for things to try from our audience. But we want to make sure we have some supplies on hand and maybe even guide the theme of the live stream so we can have a more interesting title/thumbnail. One of the tentative ideas I had was to theme the stream around reaction time (like catching a Nerf dart, or seeing if we can catch popcorn in our mouth). What ideas might y'all want to see though? -Evan

*EDIT* Thank you everyone for so many cool ideas!
