**Adam Stacoviak:** \[laughs\] "I can't read it..." "I know!" |
**Rachel Plotnick:** That's the point. |
**Adam Stacoviak:** That's the issue. |
**Jerod Santo:** You have to buy another one. You might have to buy another copy. Is there anything we didn't talk about on these two subjects now, regarding buttons and cleanliness? |
**Rachel Plotnick:** I feel like we covered a ton of stuff. No, I feel good. |
**Adam Stacoviak:** So you mentioned a Twitch coming up for your future research... But what about a website? Where can people go to find all the details of your books, and your research, and future research? |
**Rachel Plotnick:** Yeah, you can go to rachelplotnick.com, or you can find me at Indiana University. Either place, you'll get to something to do with buttons, liquids... All the things. |
**Adam Stacoviak:** All the things. And the Twitch is when again? January what? |
**Rachel Plotnick:** January 31st. It's at 2 p.m. Eastern. If you just search for "Rachel Plotnick and energy drinks", it should come up and you can find the registration... It's free, but we'd love to have some people join. |
**Adam Stacoviak:** Who should attend that? Who's that made for at this point? |
**Rachel Plotnick:** Anybody. Anybody can attend. Yeah, it's meant to be kind of academic light. So I'll be talking about academic things, but meant for a general audience. So if you're interested in energy drinks, come on by. |
**Adam Stacoviak:** Very cool. |
**Jerod Santo:** Thanks, Rachel. |
**Rachel Plotnick:** Thank you so much. This was great. |
