30 Minute Expert

Kathryn Feeney and Zack Radvanksy•www.30minuteexpertpodcast.com

Join co-hosts Zack and Katie as they learn about a different topic every week. Real-life couple Zack Radvansky and Kathryn Feeney are two curious individuals who love learning. Although Katie is in her third year of law school and Zack didn't go to college, they never run out of fascinating things to learn about together. In this podcast, every episode Katie challenges Zack to "become an expert" on a totally random topic - but the catch is, he only has 30 minutes to do it. Using the power of the internet, and a little humor and love, Zack and Katie want to prove that no matter who you are, or how much education you have, anyone can learn about anything in the world if they put their mind to it.

Silly Putty

In today's episode, Zack has 30 minutes to become an expert on... Silly Putty! A fun toy that is really kinda weird if you think about it. Why does it come in an egg?

Another happy accident story - you know how we love those - this one out of a Work War II rubber shortage. The history of silly putty includes a battle of the patent grabbers, a...

Penicillin

In today's episode, Zack has 30 minutes to become an expert on... Penicillin! Ah, penicillin... we've all heard of it - most of us have ingested it! But where did it come from?

Atlantis

In today's episode, Zack has 30 minutes to become an expert on... Atlantis! The Lost City! Was Atlantis real? Or simply a watery fantasy for the ages?

King Tut

In today's episode, Zack has 30 minutes to become an expert on... King Tut! We've all heard of him, but do any of us really know him? Zack and Katie definitely didn't! Turns out, King Tut is an incredibly unique and interesting dude, but maybe not for the reasons you think.
