Simple things that are HARD to explain!

In this episode - Taylor has put together a list of questions - topics really that seem simple - but are extremely hard to explain to say a 4 year old. This episode was filmed right after episode 1, so the boys are all getting closer and closer to their peaks - will they be able to figure it out? I can tell you that there was a ~15 minute conversation trying to decide what exactly water tastes like...so I'm not really sure if our hypothesis holds up or not!
